Description

Technical Field

[0002] In hydrogeological exploration, water level observation is an important technical means to evaluate groundwater distribution, dynamic changes and water resources management. However, traditional water level observation methods face many technical problems and challenges when faced with complex geological conditions.

[0003] First of all, traditional methods often rely on mechanical water level gauges or manual measurements. These methods are not only time-consuming and labor-intensive, but also difficult to ensure the accuracy and continuity of observations in areas with complex geological structures and variable aquifer media. The heterogeneity of the medium voids in geological boreholes will seriously affect the stability of the measurement results, making it difficult to use the water level observation data of a single borehole as a reliable basis.

[0004] Secondly, the dynamic changes of groundwater levels are affected by many factors, including geological structure, aquifer characteristics, climate change, etc. These factors lead to significant variability in groundwater levels in space and time. Traditional observation methods are difficult to meet the needs of high precision and timeliness, especially in scenarios that require real-time monitoring and long-term observation. The limitations and shortcomings of traditional methods are more prominent.

[0005] In summary, the traditional water level observation method of hydrogeological exploration has many technical problems under complex geological conditions, including insufficient observation accuracy, poor continuity, low timeliness, and measurement errors and uncertainties.

[0039] Figure 2 FIG. 1 is a flow chart of a method for measuring groundwater level according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0040] Step S201 : acquiring the gaps between adjacent water-bearing medium layers in a plurality of geological boreholes respectively to obtain a plurality of medium gaps.

[0041] Specifically, in multiple geological boreholes opened in the area to be explored, the gaps between adjacent aquifer media are measured respectively. By obtaining the gaps between multiple adjacent aquifer media layers, the groundwater level can be understood more accurately, and then the depth of the groundwater level and the change of the water level can be determined. By analyzing the water level differences between the gaps of different media, more comprehensive groundwater level distribution information can be obtained, and the distribution, recharge and attenuation of groundwater resources can be more accurately evaluated. The changing trend of the groundwater level can also be monitored, and abnormal fluctuations of the groundwater level can be discovered in time. By obtaining data on multiple medium gaps, the measurement accuracy and reliability of the groundwater level can be improved, so as to facilitate the subsequent analysis of the differences in medium characteristics between geological boreholes. Among them, the specific method of measuring the gaps between adjacent aquifer media can adopt the drilling core method. Through the cores obtained from geological boreholes, the particle size, arrangement, gap morphology and other information of the aquifer medium can be directly observed, thereby inferring the size of the gaps.

[0042] Step S202, determining a predetermined area according to a plurality of medium gaps, wherein the predetermined area includes at least two adjacent geological boreholes, one being an observation borehole and the other being a compensation borehole.

[0043] Specifically, the multiple medium voids obtained by measurement are screened, and a predetermined area is established according to the prepared geological boreholes, and two adjacent geological boreholes in the predetermined area are selected as the observation borehole and the compensation borehole respectively. By selecting two adjacent geological boreholes in the predetermined area based on the medium void characteristics between them as the observation borehole and the compensation borehole respectively, the accuracy of subsequent observation and compensation is ensured, the changes in groundwater level are better monitored, and necessary measures are taken in time. The observation borehole can monitor the height of the groundwater level in real time, while the compensation borehole can correct the observation data to ensure the accuracy and reliability of the data. By measuring between the observation borehole and the compensation borehole, the height difference of the groundwater level can be obtained, thereby determining the position of the groundwater level. Through the measurement of multiple medium voids, the situation of the groundwater level can be better understood, and the accuracy and reliability of the measurement can be improved.

[0044] Step S203, emitting a measuring light beam in the observation borehole to form a water surface laser point, and processing the water surface laser point to obtain an uncorrected water level.

[0045] Specifically, by emitting a measuring beam within a preset range according to preset parameters in the observation borehole and forming a water surface laser point, processing it based on a water level calculation model, and obtaining uncorrected water level data, accurate measurement of the groundwater level can be achieved. By using laser technology for water level observation, the accuracy of water level observation can be improved, human errors can be reduced, and the accuracy of the data can be ensured. The use of laser technology can reduce the difficulty of operation, and there is no need to directly contact the water surface. Observations can be made at a longer distance. Water surface laser points can also be quickly acquired and processed to quickly obtain uncorrected water level data. This is suitable for various geological environments and improves observation efficiency, thereby achieving non-contact high-precision water level measurement.

[0046] Step S204, emitting a compensation light beam in the compensation borehole to form a covering light spot covering the laser point on the water surface, and performing inversion calculation on the covering light spot and the uncorrected water level to obtain simulated emission parameters.

[0047] Specifically, through the compensation beam and inversion calculation, the position and water level of the water surface laser point can be accurately adjusted, thereby reducing the measurement error caused by external environmental factors or equipment errors. By obtaining the simulated emission parameters, it can help to realize real-time monitoring and accurate control of water level changes, improve the accuracy and stability of groundwater level measurement, and effectively improve the accuracy and reliability of groundwater level measurement. By emitting a compensation beam in a compensation borehole to form a covering light spot covering the water surface laser point in the observation borehole, accurate measurement of the water level can be achieved. By inverting the covering light spot and the uncorrected water level, the simulated emission parameters are obtained, so as to correct the water level measurement error caused by the unevenness of the medium voids in the observation borehole through compensation measurement, and then the actual water level situation can be determined more accurately, which can improve the precision and accuracy of water level observation, reduce the influence of human errors, and thus better understand the hydrogeological conditions.

[0048] Step S205, calculating the actual emission parameters and simulated emission parameters of the compensation light beam to obtain the compensation weight, and determining the observed water level according to the compensation weight and the uncorrected water level.

[0049] Specifically, the compensation specific gravity can be obtained by calculating the actual emission parameters and simulated emission parameters of the compensation beam based on the specific gravity calculation model. The corrected observed water level can be obtained according to the compensation specific gravity and the uncorrected water level data, thereby realizing accurate correction of the observed water level and improving the accuracy and reliability of water level observation. By timely adjusting the compensation specific gravity and the observed water level, the changes in the groundwater level can be effectively monitored, abnormal groundwater level conditions can be discovered in time and adjusted, thereby improving the measurement precision and accuracy of the groundwater level and ensuring the rational utilization and protection of groundwater resources.

[0050] From the above, it can be seen that in the embodiment of the present application, by establishing a predetermined area and selecting observation boreholes and compensation boreholes in the area, the stability and reliability of the observation data can be ensured, and continuous and accurate water level data can be obtained even under complex geological conditions, providing strong support for hydrogeological exploration; in addition, by combining optical measurement and data calculation and processing, real-time monitoring and rapid data processing of groundwater levels can be achieved, which can greatly improve the timeliness of water level observations, allowing researchers to grasp the dynamic changes of groundwater levels in a timely manner; further, through the coordinated observation of double boreholes of observation boreholes and compensation boreholes, the errors caused by factors such as medium void heterogeneity in single borehole observations can be effectively reduced. At the same time, the compensation ratio can be used to further correct the measurement deviations caused by reasons such as light refraction and scattering effects, thereby significantly improving the accuracy of water level observations.

[0051] Specifically, the above-mentioned aquifer refers to the part of the underground rock or soil layer that contains groundwater. By observing the water level of the aquifer, the changes in the groundwater level can be understood, and then the distribution, recharge and discharge of groundwater resources can be inferred. Commonly used water level observation methods include borehole water level observation, wellbore water level observation, mercury pressure gauge water level observation, etc., which can obtain water level data at different depths, so as to have a comprehensive understanding of the situation of the aquifer; the water level observation methods in the above-mentioned hydrogeological exploration usually include geological drilling. Geological drilling is a method of observing groundwater levels by digging or drilling holes underground. When conducting geological drilling, the explorers will choose a suitable location for drilling, and use a drill rig or drill rod to dig out the deep underground soil or rock until it reaches the groundwater layer. Once the borehole reaches the groundwater layer, a water level meter or other water level measurement tools are used to measure the height of the groundwater level, thereby determining the depth and horizontal position of the groundwater level, helping to analyze the distribution and flow direction of groundwater resources.

[0052] Optionally, the above screening criteria may include but are not limited to: the size of the gaps, the uniformity of distribution, etc.

[0053] Specifically, the actual emission parameters of the above-mentioned compensation light beam may include but are not limited to: the wavelength, power, divergence angle, focusing degree, beam shape, etc. of the light beam, which will directly affect the transmission and effect of the light beam and can be reasonably adjusted and optimized according to specific application requirements. It is also necessary to consider the loss and attenuation that the light beam may suffer during the transmission process to ensure that the light beam can achieve the expected effect at the target position. Among them, the wavelength of the light beam can determine the color and energy of the light beam. Light of different wavelengths has different penetration and reflection capabilities. The intensity of the light beam can determine the brightness and energy of the light beam. The greater the intensity, the greater the impact on the target. The focusing degree of the light beam can determine the focal position and size of the light beam. The higher the focusing degree, the more concentrated the energy of the light beam. The direction of the light beam can determine the emission direction and angle of the light beam, affecting the irradiation range and effect of the light beam. The mode of the light beam can determine the shape and characteristics of the light beam, such as continuous wave or pulse wave.

[0054] Specifically, the compensation ratio of the above-mentioned light beam refers to the ratio of the proportion of light beams of different components in the light beam compensation technology. Usually, the compensation ratio of the light beam is determined according to the power of each light beam. A higher-power light beam usually occupies a larger compensation ratio to ensure the balance and stability of the entire light beam system. Different beam compensation systems may have different compensation ratio settings, and the specific ratio can be determined based on the specific light beam system and actual needs.

[0055] In the specific implementation process, the predetermined area is determined according to multiple medium voids, which can be achieved through the following steps: obtaining a void threshold and determining whether the medium void is greater than the void threshold; when the medium void is greater than the void threshold, obtaining the geological borehole corresponding to the medium void to obtain multiple preparatory geological boreholes; obtaining the area to be explored that includes and only includes the preparatory geological boreholes to obtain multiple preparatory areas; determining the maximum value of the multiple preparatory areas as the predetermined area.

[0056] In this scheme, by obtaining the preparatory geological boreholes and preparatory areas, the area that needs to be explored can be accurately determined. By determining the maximum value as the predetermined area, the exploration efficiency and accuracy can be effectively improved. By finding the place where the medium void is greater than the threshold, the preparatory geological boreholes and preparatory areas can be obtained, and finally the predetermined area can be determined. By analyzing the geological boreholes and preparatory areas, the location of the groundwater level can be determined more accurately. By obtaining the void threshold, it is determined whether the medium void is greater than the threshold, thereby effectively screening out the areas that need geological drilling exploration, improving the measurement accuracy and efficiency of the groundwater level, and providing an important reference for subsequent exploration and utilization.

[0057] Specifically, a void threshold is obtained based on a model established in the region. First, a suitable void threshold is determined for subsequent screening of medium voids. The threshold is determined according to the geological characteristics of the area to be explored, the exploration target or other relevant factors. Multiple medium voids exceeding the void threshold are screened out and a preparatory geological borehole is formed. The geological borehole to which the preparatory geological borehole belongs is obtained, and the area to be explored that only contains the above-mentioned geological borehole is obtained as the preparatory area. The multiple medium voids measured are screened through the determined void threshold. If they exceed the void threshold, they are selected to form a preparatory geological borehole, and the geological borehole is determined to contain the medium voids in the preparatory geological borehole.

[0058] Then, the area to be explored where the geological borehole is located is connected as the preparation area, and the largest continuous preparation area is selected as the predetermined area. In the preparation area, there may be multiple continuous large areas. The largest continuous area is selected as the predetermined area to ensure the accuracy and reliability of subsequent observation and compensation. Two adjacent geological boreholes in the predetermined area are selected as the observation borehole and the compensation borehole respectively. Two adjacent geological boreholes are selected in the predetermined area as the observation borehole and the compensation borehole respectively. The selection of these two boreholes should be based on the medium gap characteristics, positional relationship or other relevant factors between them to ensure the accuracy of subsequent observation and compensation.

[0059] In the specific implementation process, a measuring beam is emitted in the observation borehole to form a water surface laser point, and the water surface laser point is processed to obtain an uncorrected water level. This can be achieved through the following steps: obtaining preset parameters, and emitting a measuring beam according to the preset parameters to form a plurality of preliminary laser points; eliminating abnormal points among the plurality of preliminary laser points, and the remaining preliminary laser points are water surface laser points; processing the water surface laser points based on the water level calculation model to obtain an uncorrected water level.

[0060] In this scheme, multiple preliminary laser points are formed by preset parameters and measuring beams, and water surface laser points are obtained by eliminating abnormal points. The eliminated water surface laser points are processed based on the water level calculation model to obtain the uncorrected water level. By processing the water surface laser points, the interference of abnormal points can be eliminated. Due to the influence of various factors such as water surface fluctuations and light refraction, some abnormal water surface laser points may be formed. The abnormal points are eliminated to ensure the accuracy of the measurement results, so as to ensure the accuracy of subsequent water level calculations, thereby improving the precision and accuracy of water level observations.

[0061] Optionally, the preset parameters may include but are not limited to: data such as intensity, angle and frequency of the light beam.

[0062] In the specific implementation process, the water surface laser points are processed based on the water level calculation model to obtain the uncorrected water level, which can be achieved through the following steps: According to the formula The water surface laser points are processed to obtain the uncorrected water level h, where P is the preset parameter and P max is the maximum value in the preset range of the preset parameter, P min is the minimum value in the preset range of the preset parameter, (x i ,y i , z i ) is the coordinate of the i-th water surface laser point, n is the number of water surface laser points, f(x i ,y i , z i ; P) is the water level measurement deviation caused by the preset parameters at the i-th water surface laser point.

[0063] In this scheme, the water level can be accurately measured by processing the water surface laser points and calculating the uncorrected water level h. The measurement deviation of each water surface laser point can be corrected by the above formula to obtain more accurate groundwater level data, thereby improving the precision and accuracy of water level measurement. It can effectively improve the accuracy and reliability of groundwater level measurement, and facilitate subsequent monitoring and analysis of groundwater levels.

[0064] Specifically, in the above water level calculation model, the sum of all water level heights after deviation correction is divided by the number of points n to obtain the average value of the uncorrected water level. This average value takes into account the water level measurement deviation of all points, so that the calculated uncorrected water level is close to the real water level. It is to traverse and sum all the laser points on the water surface. is the averaging factor, used to calculate the average value after summing, It is an integral expression that represents the sum of the water level measurement deviations at the point under all possible transmission parameters, one part of which represents the deviation of the preset parameter P from the minimum value P min To the maximum value P max The integral of f(x i ,y i , z i ; P) is the water level measurement deviation caused by P at the i-th point, z i -() represents the original height z of the i-th point i Subtract the water level measurement deviation caused by preset parameters, and the result is the water level height at that point after deviation correction.

[0065] In the specific implementation process, a compensation light beam is emitted in the compensation borehole to form a covering light spot covering the laser point on the water surface, and the covering light spot and the uncorrected water level are inverted and calculated to obtain the simulated emission parameters. Then, the actual emission parameters and the simulated emission parameters of the compensation light beam are calculated. Before obtaining the compensation weight, the above method also includes the following steps: obtaining the emission parameters of the compensation light beam to obtain the actual emission parameters.

[0066] In this scheme, through the emission and inversion calculation of the compensation light beam, the water surface laser points can be effectively covered and the water level can be corrected. By comparing and calculating the actual emission parameters and the simulated emission parameters, the compensation ratio can be obtained, thereby further improving the accuracy and reliability of water level observation. By obtaining the actual emission parameters and determining the exact position and depth of the groundwater level, the propagation path and reflection of the light beam in the groundwater level can be more accurately calculated, thereby obtaining more accurate groundwater level information and improving the accuracy and reliability of groundwater level measurement.

[0067] Specifically, a compensation beam is emitted in the compensation borehole to form a covering light spot on the water surface covering the laser point, so as to compensate for the water level measurement in the observation borehole. The covering light spot covers the laser point and can unify the measurement point, which is convenient for the subsequent introduction of the uncorrected water level for calculation, so as to eliminate or reduce errors caused by factors such as medium void uniformity. When emitting the compensation beam, the actual emission parameters need to be recorded for subsequent inversion calculation and specific gravity calculation.

[0068] Optionally, the above-mentioned actual emission parameters may include but are not limited to: intensity, angle and frequency of the light beam.

[0069] In the specific implementation process, the actual emission parameters and the simulated emission parameters of the compensation beam are calculated to obtain the compensation ratio, and the observed water level is determined based on the compensation ratio and the uncorrected water level. This can be achieved through the following steps: based on the ratio calculation model, the actual emission parameters and the simulated emission parameters are calculated to obtain the compensation ratio; based on the compensation ratio and the uncorrected water level, the observed water level is determined.

[0070] In this scheme, the actual emission parameters and the simulated emission parameters are calculated based on the specific gravity calculation model to obtain the compensated specific gravity, and the observed water level is determined based on the compensated specific gravity and the uncorrected water level. This can effectively correct the errors in the groundwater level measurement and improve the accuracy and reliability of the water level observation. Through the calculation of the specific gravity calculation model and the compensated specific gravity, the correction compensation of the uncorrected water level can be achieved, and the groundwater level can be determined more accurately. This can effectively reduce the measurement errors caused by factors such as medium void heterogeneity, improve the accuracy and reliability of water level observation, and the obtained observed water level can provide strong data support for subsequent hydrogeological exploration and analysis.

[0071] In the specific implementation process, the actual transmission parameters and simulated transmission parameters are calculated based on the specific gravity calculation model to obtain the compensation specific gravity, which can be achieved through the following steps: According to the formula For the actual transmission parameter P a and simulated emission parameters P m Calculate and get the compensation ratio α, where μ, σ is the parameter calculation coefficient.

[0072] In this scheme, the difference between the actual emission parameters and the simulated emission parameters can be adjusted by calculating the compensation ratio α, eliminating the error caused by the difference between the actual emission parameters and the simulated emission parameters, making the observation results more accurate and reliable. At the same time, the parameter calculation coefficient is determined according to the specific geological conditions, exploration needs and experimental data to ensure the accuracy and applicability of the model, thereby improving the stability and accuracy of the measurement in actual measurement and better meeting the needs of groundwater level monitoring.

[0073] In the specific implementation process, the observed water level is determined according to the compensation ratio and the uncorrected water level, which can be achieved through the following steps: According to the formula H=h×α+γ, the observed water level H is calculated, where h is the uncorrected water level, α is the compensation ratio, and γ is the adjustment coefficient.

[0074] In this scheme, the observed water level calculated by this formula can more accurately reflect the actual groundwater level. By adjusting the compensation ratio and the adjustment coefficient, the uncorrected water level can be corrected to obtain a more accurate groundwater level observation value. Through the ratio calculation model, the uncorrected water level can be effectively corrected and compensated to obtain a more accurate and reliable observed water level. It can also monitor the changes in the groundwater level and promptly discover the changing trend of the groundwater level. Under complex geological conditions, it can significantly improve the accuracy and stability of water level observation.

[0075] Specifically, the above-mentioned compensation ratio and adjustment coefficient can be adjusted according to actual conditions to ensure the accuracy and stability of the observed water level. The compensation ratio can be adjusted according to the characteristics of the groundwater level and the measurement environment to eliminate the influence of external factors on water level observation. The adjustment coefficient can correct instrument errors or environmental factors to further improve the accuracy of water level observation. It can be artificially set to zero, or the observed water level can be further adjusted based on experience or other standards.

[0076] The present application embodiment also provides a kind of measuring device of underground water level, it should be noted that the measuring device of underground water level of the present application embodiment can be used to perform the measuring method for underground water level provided by the present application embodiment. The device is used to realize the above-mentioned embodiment and preferred implementation mode, and the description has been made no more. As used below, the term "module" can realize the combination of software and / or hardware of predetermined function. Although the device described in the following embodiments is preferably realized by software, the realization of hardware, or the combination of software and hardware is also possible and conceived.

[0077] The following is an introduction to the groundwater level measuring device provided in the embodiment of the present application.

[0078] Figure 3 is a structural block diagram of a groundwater level measuring device according to an embodiment of the present application. Figure 3 As shown, the device includes: an acquisition unit 31, a determination unit 32, a processing unit 33, a first calculation unit 34 and a second calculation unit 35.

[0079] The acquisition unit 31 is used to respectively acquire the voids between adjacent water-bearing medium layers in a plurality of geological boreholes to obtain a plurality of medium voids.

[0080] The determination unit 32 is used to determine a predetermined area according to a plurality of medium gaps, wherein the predetermined area includes at least two adjacent geological boreholes, one of which is an observation borehole and the other is a compensation borehole.

[0081] The processing unit 33 is used to emit a measuring light beam in the observation borehole to form a water surface laser point, and process the water surface laser point to obtain an uncorrected water level.

[0082] The first calculation unit 34 is used to emit a compensation light beam in the compensation borehole to form a covering light spot covering the laser point on the water surface, and perform inversion calculation on the covering light spot and the uncorrected water level to obtain simulated emission parameters.

[0083] The second calculation unit 35 is used to calculate the actual emission parameters and the simulated emission parameters of the compensation light beam to obtain the compensation ratio, and determine the observed water level according to the compensation ratio and the uncorrected water level.

[0084] This scheme can ensure the stability and reliability of observation data by establishing a predetermined area and selecting observation boreholes and compensation boreholes in the area. Even under complex geological conditions, continuous and accurate water level data can be obtained, providing strong support for hydrogeological exploration. In addition, by combining optical measurement and data calculation and processing, real-time monitoring and rapid data processing of groundwater levels can be achieved, which can greatly improve the timeliness of water level observations and enable researchers to grasp the dynamic changes of groundwater levels in a timely manner. Furthermore, through the coordinated observation of double boreholes of observation boreholes and compensation boreholes, the errors caused by factors such as medium void heterogeneity in single borehole observations can be effectively reduced. At the same time, the use of compensation weight can further correct the measurement deviations caused by reasons such as light refraction and scattering effects, thereby significantly improving the accuracy of water level observations.

[0085] In the specific implementation process, the predetermined area is determined according to multiple medium voids, which can be achieved through the following steps: obtaining a void threshold and determining whether the medium void is greater than the void threshold; when the medium void is greater than the void threshold, obtaining the geological borehole corresponding to the medium void to obtain multiple preparatory geological boreholes; obtaining the area to be explored that includes and only includes the preparatory geological boreholes to obtain multiple preparatory areas; determining the maximum value of the multiple preparatory areas as the predetermined area.

[0086] In this scheme, by obtaining the preparatory geological boreholes and preparatory areas, the area that needs to be explored can be accurately determined. By determining the maximum value as the predetermined area, the exploration efficiency and accuracy can be effectively improved. By finding the place where the medium void is greater than the threshold, the preparatory geological boreholes and preparatory areas can be obtained, and finally the predetermined area can be determined. By analyzing the geological boreholes and preparatory areas, the location of the groundwater level can be determined more accurately. By obtaining the void threshold, it is determined whether the medium void is greater than the threshold, thereby effectively screening out the areas that need geological drilling exploration, improving the measurement accuracy and efficiency of the groundwater level, and providing an important reference for subsequent exploration and utilization.

[0087] In the specific implementation process, a measuring beam is emitted in the observation borehole to form a water surface laser point, and the water surface laser point is processed to obtain an uncorrected water level. This can be achieved through the following steps: obtaining preset parameters, and emitting a measuring beam according to the preset parameters to form a plurality of preliminary laser points; eliminating abnormal points among the plurality of preliminary laser points, and the remaining preliminary laser points are water surface laser points; processing the water surface laser points based on the water level calculation model to obtain an uncorrected water level.

[0088] In this scheme, multiple preliminary laser points are formed by preset parameters and measuring beams, and water surface laser points are obtained by eliminating abnormal points. The eliminated water surface laser points are processed based on the water level calculation model to obtain the uncorrected water level. By processing the water surface laser points, the interference of abnormal points can be eliminated. Due to the influence of various factors such as water surface fluctuations and light refraction, some abnormal water surface laser points may be formed. The abnormal points are eliminated to ensure the accuracy of the measurement results, so as to ensure the accuracy of subsequent water level calculations, thereby improving the precision and accuracy of water level observations.

[0089] In the specific implementation process, the water surface laser points are processed based on the water level calculation model to obtain the uncorrected water level, which can be achieved through the following steps: According to the formula The water surface laser points are processed to obtain the uncorrected water level h, where P is the preset parameter and P max is the maximum value in the preset range of the preset parameter, P min is the minimum value in the preset range of the preset parameter, (x i ,y i , z i ) is the coordinate of the i-th water surface laser point, n is the number of water surface laser points, f(x i ,y i , z i ; P) is the water level measurement deviation caused by the preset parameters at the i-th water surface laser point.

[0090] In this scheme, the water level can be accurately measured by processing the water surface laser points and calculating the uncorrected water level h. The measurement deviation of each water surface laser point can be corrected by the above formula to obtain more accurate groundwater level data, thereby improving the precision and accuracy of water level measurement. It can effectively improve the accuracy and reliability of groundwater level measurement, and facilitate subsequent monitoring and analysis of groundwater levels.

[0091] In the specific implementation process, a compensation light beam is emitted in the compensation borehole to form a covering light spot covering the laser point on the water surface, and the covering light spot and the uncorrected water level are inverted and calculated to obtain the simulated emission parameters. Then, the actual emission parameters and the simulated emission parameters of the compensation light beam are calculated. Before obtaining the compensation weight, the above method also includes the following steps: obtaining the emission parameters of the compensation light beam to obtain the actual emission parameters.

[0092] In this scheme, through the emission and inversion calculation of the compensation light beam, the water surface laser points can be effectively covered and the water level can be corrected. By comparing and calculating the actual emission parameters and the simulated emission parameters, the compensation ratio can be obtained, thereby further improving the accuracy and reliability of water level observation. By obtaining the actual emission parameters and determining the exact position and depth of the groundwater level, the propagation path and reflection of the light beam in the groundwater level can be more accurately calculated, thereby obtaining more accurate groundwater level information and improving the accuracy and reliability of groundwater level measurement.

[0093] In the specific implementation process, the actual emission parameters and the simulated emission parameters of the compensation beam are calculated to obtain the compensation ratio, and the observed water level is determined based on the compensation ratio and the uncorrected water level. This can be achieved through the following steps: based on the ratio calculation model, the actual emission parameters and the simulated emission parameters are calculated to obtain the compensation ratio; based on the compensation ratio and the uncorrected water level, the observed water level is determined.

[0094] In this scheme, the actual emission parameters and the simulated emission parameters are calculated based on the specific gravity calculation model to obtain the compensated specific gravity, and the observed water level is determined based on the compensated specific gravity and the uncorrected water level. This can effectively correct the errors in the groundwater level measurement and improve the accuracy and reliability of the water level observation. Through the calculation of the specific gravity calculation model and the compensated specific gravity, the correction compensation of the uncorrected water level can be achieved, and the groundwater level can be determined more accurately. This can effectively reduce the measurement errors caused by factors such as medium void heterogeneity, improve the accuracy and reliability of water level observation, and the obtained observed water level can provide strong data support for subsequent hydrogeological exploration and analysis.

[0095] In the specific implementation process, the actual transmission parameters and simulated transmission parameters are calculated based on the specific gravity calculation model to obtain the compensation specific gravity, which can be achieved through the following steps: According to the formula For the actual transmission parameter P a and simulated emission parameters P m Calculate and get the compensation ratio α, where μ, σ is the parameter calculation coefficient.

[0096] In this scheme, the difference between the actual emission parameters and the simulated emission parameters can be adjusted by calculating the compensation ratio α, eliminating the error caused by the difference between the actual emission parameters and the simulated emission parameters, making the observation results more accurate and reliable. At the same time, the parameter calculation coefficient is determined according to the specific geological conditions, exploration needs and experimental data to ensure the accuracy and applicability of the model, thereby improving the stability and accuracy of the measurement in actual measurement and better meeting the needs of groundwater level monitoring.

[0097] In the specific implementation process, the observed water level is determined according to the compensation ratio and the uncorrected water level, which can be achieved through the following steps: According to the formula H=h×α+γ, the observed water level H is calculated, where h is the uncorrected water level, α is the compensation ratio, and γ is the adjustment coefficient.

[0098] In this scheme, the observed water level calculated by this formula can more accurately reflect the actual groundwater level. By adjusting the compensation ratio and the adjustment coefficient, the uncorrected water level can be corrected to obtain a more accurate groundwater level observation value. Through the ratio calculation model, the uncorrected water level can be effectively corrected and compensated to obtain a more accurate and reliable observed water level. It can also monitor the changes in the groundwater level and promptly discover the changing trend of the groundwater level. Under complex geological conditions, it can significantly improve the accuracy and stability of water level observation.
