Description

Technical Field

[0001] This invention relates to the field of data processing technology, specifically to a groundwater level dynamic monitoring device and monitoring method. Background Technology

[0002] Groundwater refers to water bodies existing in the pores, fissures, and karst caves of rocks and soil below the ground surface. In municipal construction and other engineering projects, to facilitate foundation construction and provide sufficient construction space, the design and excavation of foundation pits are usually carried out before the project starts. However, groundwater is one of the most uncertain factors in the foundation pit construction process. Changes in groundwater level not only lead to changes in soil and water pressure and an increase in soil protection, but also exacerbate the instability of the soil around the foundation pit, thereby increasing the stress risk on the support structure and potentially triggering a chain reaction such as surface subsidence in the surrounding environment. To reduce these risks and minimize negative impacts on the surrounding environment, before excavating the foundation pit, it is necessary to understand the distribution of groundwater based on geological and hydrological data and actual site conditions, and to scientifically formulate an excavation plan. At the same time, it is essential to monitor the dynamic changes in groundwater level in real time, issue early warnings for dangerous water levels, and implement preventive measures such as waterproofing, drainage, and dewatering. Current technologies typically acquire groundwater level data through monitoring and plotting dynamic groundwater level curves to predict future changes in water levels, set early warning thresholds, and promptly detect and alert for water level anomalies. This provides real-time data support for operations such as foundation pit dewatering and support, helping to ensure construction safety and reduce engineering risks and cost increases caused by groundwater level changes. However, when predicting groundwater level trends to assess the risk of water level anomalies, current technologies often rely solely on dynamic curves plotted from monitoring data for simulation and prediction, failing to consider scenarios where geological structures significantly influence water level changes. This approach results in low accuracy in predicting groundwater level trends and hinders effective risk warning. Summary of the Invention

This includes: determining the possibility that the target underground water area and the current underground water area are interconnected and have groundwater migration behavior based on the difference sequence between the target underground water area and the current underground water area; and correcting the estimated water level height based on the last element in the difference sequence of the target underground water area, the distance between the water level sensors of the target underground water area and the current underground water area, and the possibility, to obtain the corrected water level height.

[0009] Preferably, determining the possibility that the target underground water body and the current underground water body are interconnected and have groundwater migration behavior based on the difference sequence of water level heights between the target underground water body and the current underground water body includes: determining the possibility that the target underground water body and the current underground water body are interconnected and have groundwater migration behavior based on the superposition value of each element in the difference sequence of water level heights of the current underground water body and the superposition value of each element in the difference sequence of water level heights of the target underground water body. The superposition value of each element in the difference sequence of water level heights of the target underground water body includes the first superposition value of each element in the difference sequence of water level heights of the first target underground water body and the second superposition value of each element in the difference sequence of water level heights of the second target underground water body.

Detailed Implementation

[0017] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a groundwater level dynamic monitoring device and method proposed according to the present invention. In the following description, different "one embodiment" or "one embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0019] The specific scheme of the groundwater level dynamic monitoring method provided by the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1: Please see Figure 1 The diagram illustrates a flowchart of a groundwater level dynamic monitoring method according to an embodiment of the present invention, comprising: Step S101: Obtain the water level height of the underground water area at each collection time in the construction area to form a water level height sequence. Determine the difference sequence based on the elements in the water level height sequence, and predict the estimated water level height of the underground water area at future times based on the current water level height sequence.

[0021] Specifically, in this embodiment of the invention, when predicting changes in groundwater levels, the environment of the underground water body has a significant impact on the water level changes, and this environmental influence factor needs to be considered during the prediction process. In specific implementation, such as... Figure 2 As shown, Figure 2 This invention provides a schematic diagram of water level monitoring, calibration, and transmission for underground water bodies in a construction area, as provided in one embodiment. The embodiment first determines the construction area, then uses techniques such as ground-penetrating radar and resistivity methods to survey the geological distribution within the construction area, determining the locations of various underground water bodies. During excavation, pressure-type water level sensors are deployed at the corresponding locations in advance to monitor changes in the water level of various underground water bodies within the construction area in real time. It is assumed that there are currently a total of [number missing] monitorable underground water bodies. A calibration gauge was installed near the water level sensor. By periodically obtaining the true values ​​of manual observations, a linear regression model was established by combining the observed true values ​​with the values ​​measured by the water level sensor. The water level data measured by the water level sensor was dynamically calibrated, and the calibration data was transmitted to the central control system via a wireless communication module.

[0022] Furthermore, in this embodiment of the invention, the frequency of water level data acquisition by the monitoring water level sensor is set to once per minute, and the subsequent water level data change trend is predicted based on the data from the most recent hour. (The text then repeats the first instance, which seems unrelated and likely refers to a different invention.) Taking a subsurface water body as an example, let the set of dynamically calibrated water level height data relative to the surface level obtained from monitoring within the past hour be denoted as [data missing]. As the sequence of water level heights for the i-th underground water area. This represents the water level height of the i-th underground water body at time j. According to another embodiment of the present invention, predicting the estimated future water level height of the current underground water body based on the current water level height sequence includes: simulating and plotting a dynamic curve of the current underground water body's water level changing over time using the least squares method; and using the dynamic curve to predict the estimated future water level height of the current underground water body. Specifically, the central control system simulates and plots the dynamic curve of the water level height data of each underground water body changing over time using the least squares method based on the water level data in the calibrated water level height sequence, and predicts the trend of water level changes in the underground water body over a subsequent period based on the dynamic curve.

[0023] Furthermore, due to interconnections or differences in soil moisture content, groundwater migrates between different underground water bodies due to pressure differences or variations in water content, leading to correlations in water level changes among these migrating water bodies. The location and environment of each underground water body differ, as do the locations and migration patterns of other underground water bodies with which it migrates, necessitating targeted analysis and calculations for each individual underground water body. This invention embodiment uses the first... For each groundwater body, other groundwater bodies with which groundwater migration occurs are selected, and the groundwater migration between them is calculated. The results are then used to analyze the situation of the first groundwater body. The subsequent water level changes in the underground water bodies were revised. For example, Figure 3 As shown, Figure 3 This is a schematic diagram illustrating migration behavior between different underground water bodies, as provided in one embodiment of the present invention. Figure 3 As shown, there are connecting gaps or channels between several underground water bodies. Due to atmospheric pressure, the groundwater in these underground water bodies will migrate from the high water level area to the low water level area until the water levels between the underground water bodies are level. Therefore, this type of underground water body group can be screened based on the existing changes in the water level of the underground water bodies.

[0024] Furthermore, in this embodiment of the invention, after obtaining the water level height sequence, the data of the underground water area to be analyzed is acquired and calculated, that is, the detected data is obtained. Data set of water level changes in an underground water body over the past hour Then calculate the dataset. The difference sequence within the data set Subtracting the previous value from the subsequent value, denoted as This is used to represent the water level change of the i-th underground water body over the past hour, that is, the difference sequence of the water level change of the i-th underground water body over the past hour. This represents the change in water level at time j in the i-th underground water area. This represents the water level height of the i-th underground water body at the j-th moment. This represents the water level height of the i-th underground water body at time j-1.

[0025] Step S102: Based on the maximum and minimum values ​​in the difference sequence and water level height sequence, select target underground water bodies from other water bodies in the construction area that are interconnected with the current underground water bodies and have groundwater migration behavior.

[0026] Specifically, among interconnected underground water bodies, the water level of some underground water bodies rises while the water level of the other underground water bodies falls. Both tend towards a certain midpoint between their water levels. Therefore, the falling water level will not be lower than the rising water level. This can be used to initially screen other underground water bodies that may be connected to the underground water body to be analyzed, i.e., the target underground water body. According to another embodiment of the present invention, the selection of target underground water bodies that are interconnected with the current underground water body and exhibit groundwater migration behavior from other water bodies in the construction area based on the maximum and minimum values ​​in the difference sequence and the water level height sequence includes: symbolizing the sum of each element in the difference sequence to obtain the recent change trend of the underground water body, wherein, when the recent change trend of the underground water body is a first value, it indicates that the water level of the underground water body is in an upward trend; when the recent change trend of the underground water body is a second value, it indicates that the water level of the underground water body is in a downward trend; when the recent change trend of the underground water body is a third value, it indicates that the water level of the underground water body is stabilizing; the first value is greater than the third value, and the third value is greater than the second value; determining the recent change amplitude of the underground water body according to the maximum and minimum values ​​in the water level height sequence; and selecting target underground water bodies that are interconnected with the current underground water body and exhibit groundwater migration behavior from other water bodies in the construction area based on the recent change trend and the recent change amplitude.

[0027] Specifically, in this embodiment of the invention, the first value can be 1, the second value can be -1, and the third value can be 0. In this embodiment, taking the i-th underground water body as an example, the difference sequence of the i-th underground water body is obtained. The sum of all elements is denoted as ,right Obtain by symbolization , is used to represent the recent changing trend of the i-th underground water body. Wherein, Represents a symbolic function. This indicates that the water level of the i-th underground water body is on an upward trend. This indicates that the water level of the i-th underground water body is in a downward trend. This indicates that the water level of the i-th underground water body is stable.

[0028] Furthermore, this embodiment of the invention obtains the water level height sequence of the i-th underground water body. The maximum value in is The minimum value is Calculate the water level height sequence of the i-th underground water body accordingly. The range is denoted as This represents the recent change in the water level of the i-th underground water body. Thus, according to the above method, this embodiment of the invention calculates the recent trend of water level changes for n underground water bodies as follows: The recent change range is .

[0029] Furthermore, according to another embodiment of the present invention, based on recent change trends and recent change magnitudes, selecting target underground water bodies from other water bodies in the construction area that are interconnected with the current underground water body and exhibit groundwater migration behavior includes: determining underground water bodies whose sum of recent change trends with the current underground water body equals a third value and satisfies a first condition, which are designated as the first target underground water bodies with rising water levels. If the recent change trend of the current underground water body is the first value, then the first condition is: the maximum value in the water level height sequence of the current underground water body is less than the minimum value in the water level height sequence of other water bodies; if the recent change trend of the current underground water body is the second value, then the first condition is: the maximum value in the water level height sequence of other water bodies is less than the minimum value in the water level height sequence of the current underground water body. Determine the maximum and minimum water level values ​​in the first target underground water area; determine the underground water area whose difference from the current recent trend of the underground water area is equal to a third value and meets the second condition, which is the second target underground water area with declining water level. The second condition is that the maximum value in the water level height sequence of other water areas is less than the minimum water level value and the current recent trend of the underground water area is the first value, and the maximum water level value is less than the minimum water level height sequence of other water areas and the current recent trend of the underground water area is the second value; the target underground water area includes the first target underground water area and the second target underground water area.

[0030] Specifically, taking the i-th underground water body as an example, this embodiment of the invention first selects several... (The water level changes in opposite directions) and Groundwater areas (where water levels converge towards a certain intermediate value). Record the total amount of water obtained. A subsurface water body that meets the first condition described above is designated as the first target subsurface water body, and in this embodiment of the invention, it is designated as follows: Then take The maximum value in the sequence of water level heights of all underground water bodies and minimum value .in, This represents the recent trend of change in the i-th underground water body. Indicates the first Recent trends in underground water bodies. Represents the sequence of water level heights in the i-th underground water area. The maximum value in. Represents the sequence of water level heights in the i-th underground water area. The minimum value in. Indicates the first The maximum value in a sequence of water level heights in an underground water body. Indicates the first The minimum value in a sequence of water level heights in an underground water body.

[0031] More specifically, randomly select several more to satisfy (The water level changes in a consistent trend) and For underground water bodies where water levels tend towards a certain intermediate value, record the total amount of water obtained. The first underground water body that meets the above conditions, namely the second target underground water body, is designated as follows: . This represents the recent trend of change in the i-th underground water body. Indicates the first Recent trends in underground water bodies. Indicates the first The maximum value in a sequence of water level heights in an underground water body. Indicates the first The minimum value in a sequence of water level heights in an underground water body. express The maximum value in the sequence of water level heights for all underground water bodies. express The minimum value in the sequence of water level heights of all underground water bodies.

[0032] Step S103: Based on the difference sequence between the target underground water area and the current underground water area, and the distance between the water level sensor of the target underground water area and the water level sensor of the current underground water area, the estimated water level height is corrected to obtain the corrected water level height.

[0033] Specifically, the above embodiments of the present invention have yielded a total of One target underground water area, The target underground water area and the first The underground water bodies are interconnected and exhibit groundwater migration behavior. In another embodiment of the present invention, the estimated water level is corrected based on the difference sequence between the target underground water body and the current underground water body, and the distance between the water level sensors of the target and current underground water bodies, to obtain the corrected water level height. This includes: determining the probability that the target and current underground water bodies are interconnected and exhibit groundwater migration behavior based on the difference sequence between their water level heights; and correcting the estimated water level height based on the last element of the difference sequence of the target underground water body, the distance between the water level sensors of the target and current underground water bodies, and the probability, to obtain the corrected water level height.

[0034] In determining the possibility that the target underground water area and the current underground water area are interconnected and have groundwater migration behavior, according to another embodiment of the present invention, the possibility of the target underground water area and the current underground water area being interconnected and having groundwater migration behavior is determined based on the difference sequence of water level heights between the target underground water area and the current underground water area. This includes: the superposition value of each element in the difference sequence of water level heights of the current underground water area and the superposition value of each element in the difference sequence of water level heights of the target underground water area. The superposition value of each element in the difference sequence of water level heights of the target underground water area includes the first superposition value of each element in the difference sequence of water level heights of the first target underground water area and the second superposition value of each element in the difference sequence of water level heights of the second target underground water area.

[0035] In this embodiment of the invention, the method obtained in the above embodiments is described. Taking a target underground water area as an example, the assessment of the above-mentioned data... The target underground water area and the first The possibility of interconnected underground water bodies and groundwater migration is denoted as . The following formula is used for calculation. : In the above formula, express The target underground water area and the first These underground water bodies are interconnected and there is a possibility of groundwater migration. Indicates the first The first underground water area The change in water level at each time point compared to the previous time point. express The first target underground water area The first underground water area The change in water level at each time point compared to the previous time point. express The first target underground water area The first underground water area The change in water level at each time point compared to the previous time point. This represents an exponential function. In the formula, the numerator represents the value of the target underground water body in relation to the first exponential function. The water level changes of the two underground water bodies show opposite trends. An underground water body at any time The total value of water level changes; the denominator represents the value of the target underground water area in relation to the first... The water level changes of the groundwater bodies have the same trend, including the first one. Including underground waters An underground water body at any time The total value of water level changes. Indicates the first The first underground water area The ratio of water level changes between two groups of water bodies with the same and opposite trends at each time point; the ratio of changes at each time point is relatively consistent. The target underground water area and the first The higher the likelihood that interconnected underground water bodies exhibit groundwater migration behavior, the better; Multiply by Then accumulate to obtain This represents the operation of subtracting each pair of data in the water level change ratio set and then summing all the differences. It is used to reflect the overall difference between adjacent data in the water level change ratio set. The smaller this value is, the closer the overall water level change ratio is. That is, the ratio of the change of the relative change trends at each moment is similar, and the more likely these underground water bodies are to be interconnected.

[0036] Specifically, if The value of is 0, at this time let The target underground water area and the first The probability that several underground water bodies are interconnected and that there is groundwater migration is 1.

[0037] In conclusion, The comprehensive representation of the first The underground water area and the screened results The target underground water bodies are interconnected and have the potential for groundwater migration and relocation. The larger this value, the more likely these underground water bodies are to be interconnected.

[0038] Furthermore, embodiments of the present invention employ multiple screenings and... Combining target underground water bodies with consistent and opposite water level trends, and calculating the probability of interconnection between these combinations. Value, take one of them The combination of underground water bodies with the largest value is marked as having multiple underground water bodies connected to the i-th underground water body, and its value is recorded as follows: Value The water levels of these water bodies change as groundwater migrates between them.

[0039] Furthermore, embodiments of the present invention, through the above steps, filter to obtain a series of results related to the first... These are interconnected underground water bodies that exhibit groundwater migration. Because groundwater migration is a dynamic process, there is a certain delay between the flowing water in other underground water bodies. Therefore, recent changes in the water levels of other underground water bodies all affect the first... The anticipated subsequent water level changes in the first underground water body will have some impact. Its impact on the second underground water body can be assessed based on the water level changes in other underground water bodies. The influence of the groundwater level and the correction of its subsequent trend are discussed. In another embodiment of the present invention, the estimated water level height is corrected based on the last element in the difference sequence of the target groundwater, the distance between the target groundwater level sensor and the current groundwater level sensor, and the probability, to obtain the corrected water level height. This includes: determining the ratio between the last element in the difference sequence of the target groundwater and the distance; weighting the probability according to the ratio to obtain a weighted probability; and correcting the estimated water level height based on the weighted probability to obtain the corrected water level height.

[0040] Specifically, in this embodiment of the invention, the most recent water level change data of various underground water areas are first obtained, that is, the difference sequence of each underground water area is recorded. The last element value in the array is denoted by the first element. The changing trends of underground water bodies The most recent water level change in the underground water area is as follows: Similarly, the first The underground water bodies show opposite trends. The most recent water level change in the underground water area is as follows: The closer the underground water bodies are, the shorter their channels may be, the less time the groundwater needs to migrate, the more rapid its impact on the water level, and the greater the impact. Record the distance between the water level gauge sensors in each target underground water body and the... The distances of the water level gauge sensors in the underground water bodies are respectively .

[0041] Furthermore, according to the above embodiments of the present invention, the first [data] obtained by fitting the recently monitored data is [further details needed]. The dynamic curve of the water level change in the groundwater area is used to obtain a preliminary prediction of the next moment's water level. The estimated water level height of the underground water area Based on the above data, the estimated water level height is... After correction, the corrected water level height is obtained, and denoted as the corrected water level height. , The calculation formula is as follows: In the above formula, Indicates the first Corrected water level height for underground water bodies. Indicates the first The estimated water level of an underground water body. Indicates the target underground water area and the first The greater the probability that several underground water bodies are interconnected and exhibit groundwater migration, the greater the impact of changes in the water levels of other underground water bodies on the first. The greater the impact of the first underground water body, the more significant the influence of other underground water body water level data on the second. The higher the degree of correction in subsequent predictions of groundwater level, the better. and They are respectively with the first Both the recent changes in groundwater level trends (which are opposite to or the same as those of groundwater bodies, and whose change values ​​also have opposite or the same signs) will affect the recent changes in groundwater level. Changes in the water level of underground water bodies. and The distances from the aforementioned underground water bodies to the first The closer the distance between two underground water bodies, the faster the groundwater migrates, and the greater the impact. The expression represents the normalization function. In this embodiment, the maximum and minimum value normalization method is used for normalization processing. The maximum and minimum value normalization method is existing technology and will not be described in detail here.

[0042] Furthermore, by comprehensively considering all aspects of the first... The changes in the groundwater level of the first target groundwater body have an impact on the changes in the groundwater level of the second target groundwater body. The estimated water level of each underground water body is then corrected to obtain the corrected water level height.

[0043] Step S104: Issue an early warning for abnormal water levels in the underground waters of the construction area based on the corrected water level line height.

[0044] Specifically, in this embodiment of the invention, the corrected groundwater level is uploaded to the system and compared with the warning value to provide timely warnings of abnormal groundwater levels, allowing for advance dewatering of the foundation pit and preventing construction risks. In another embodiment of the invention, providing warnings of abnormal groundwater levels in the construction area based on the corrected groundwater level includes: determining an abnormal groundwater level in the construction area when the corrected groundwater level exceeds the warning value. The warning value can be determined based on the actual scenario, and this embodiment of the invention does not impose any limitations on it.

[0045] This invention, through acquiring water level heights at various collection times and forming a sequence, enables real-time monitoring of the dynamic changes in groundwater levels. Combined with a difference sequence, it accurately captures sudden water level changes. Predicting future water level heights based on the water level height sequence allows for early warning of potential abnormal fluctuations, providing construction teams with sufficient response time. Furthermore, based on the estimated water level heights, and using the difference sequence, maximum, and minimum values ​​of the water level height sequences for each underground water body, target underground water bodies connected to the current underground water body and exhibiting groundwater migration behavior are selected from other water bodies. This considers the influence of geological structures on water level changes, achieving accurate identification of the correlation between underground water bodies. On this basis, the estimated water level height is corrected by considering the distance between the target underground water body and the current underground water level sensor, further eliminating errors from single monitoring data. This makes the final corrected water level height more closely reflect the actual situation of the underground water body, providing reliable data support for subsequent water level anomaly assessments, improving the prediction accuracy of groundwater level trends, and thus enabling effective risk warning.
