Description

Technical Field

[0001] The present invention relates to the field of dynamic compaction monitoring technology, and specifically to a method, system, medium and device for monitoring dynamic compaction settlement. Background Art

[0002] Dynamic compaction method is a construction method widely used in the field of foundation treatment. It has great technical and economic advantages for complex site formation projects such as cutting peaks and filling valleys, and land reclamation. Compared with pile foundation or other composite foundation construction techniques, under the same engineering geological conditions, dynamic compaction method and its composite techniques have the advantages of energy saving, environmental protection, economy and high efficiency.

[0003] The dynamic compaction treatment of the foundation includes tamping the foundation. This process is instantaneous, hidden and complex, which brings certain difficulties to monitoring and quality control. The quality control indicators of the dynamic compaction method mainly include tamping amount, tamping amount, tamping times, etc. The quality monitoring of the traditional dynamic compaction method mainly relies on manual visual inspection, measurement with a ruler, and hand notes. Errors are prone to occur in the process, resulting in deviations between the results obtained after the dynamic compaction treatment of the foundation and the expected target. Summary of the invention

[0004] The present application provides a method, system, medium and equipment for monitoring the amount of strong compaction settlement, which realizes quantitative monitoring and active control of strong compaction settlement, so that the results obtained after strong compaction treatment of the foundation are more in line with the expected goals.

[0005] In a first aspect, the present application provides a method for monitoring the amount of strong compaction, the method comprising:

[0006] Acquire all first tamping parameters of the target foundation, and generate a tamping plan according to the first tamping parameters;

[0007] Acquire a second tamping parameter currently being performed according to the tamping plan, and determine a deviation value of the second tamping parameter according to the tamping plan;

[0008] The tamping plan is adjusted according to the deviation value, and the target foundation is tamped according to the adjusted tamping plan.

[0009] By adopting the above technical solution, a pre-formulated phased tamping plan for the target foundation is obtained, which includes the parameters of each tamping and the corresponding theoretical settlement. Then, in the actual construction process, the actual settlement of each tamping stage is monitored, and the settlement deviation value is calculated by comparing it with the theoretical value. If the settlement deviation value exceeds the allowable range, it means that the actual tamping effect is different from the expected one. At this time, all subsequent tamping sub-plans starting from the current stage are adjusted according to the settlement deviation value, so that the subsequent tamping sub-plans are appropriately changed to reduce the deviation between the actual tamping effect and the theoretical expectation. In this way, through closed-loop feedback control, the tamping plan can be continuously optimized, so that the result obtained after the strong tamping treatment of the foundation is more in line with the expected goal.

[0010] Optionally, obtaining the tamping plan for the target foundation includes: obtaining historical tamping information that has been carried out on the target foundation according to a preset plan; obtaining soil parameters of the target foundation and a target settlement depth of the tamping, and establishing a tamping simulation model based on the soil parameters and the historical tamping information; and determining the tamping plan for the target foundation according to the tamping simulation model and the target settlement depth.

[0011] By adopting the above technical solution, the historical tamping data and soil parameters of the target foundation are obtained, and the plan is determined by establishing a tamping simulation model. Specifically, the soil parameters of the foundation are used to establish an initial simulation model, and then the historical tamping parameters and the corresponding settlement are repeatedly used as samples to input the model for training, so that the model gradually approaches the actual situation, and an iteratively optimized tamping simulation model is obtained. Based on this model, the designed target settlement can be input, and through multiple simulation calculations, the combination of parameters such as the number of tamping times, frequency, and force required to achieve the target settlement under the current soil conditions can be scientifically and reasonably predicted, that is, a more accurate tamping plan can be obtained.

[0012] Optionally, the historical tamping information includes the number of historical tamping times, historical tamping parameters corresponding to each of the historical tamping times, and historical settlement depths after tamping the target foundation according to each of the historical tamping parameters. Establishing a tamping simulation model based on the soil parameters and the historical tamping information includes: establishing a virtual foundation to be tamped according to the soil parameters; constructing an initial tamping simulation model, simulating the tamping of the foundation to be tamped on the initial tamping simulation model according to the historical tamping parameters corresponding to each of the historical tamping times, and taking the historical settlement depths after tamping the target foundation with each of the historical tamping parameters as simulated settlement depths; using the historical tamping parameters corresponding to each of the historical tamping times, and the corresponding simulated settlement depths, as training samples, to train the initial tamping simulation model to obtain a trained tamping simulation model.

[0013] By adopting the above technical scheme, a virtual foundation to be compacted is established according to the actual soil parameters, and an initial compaction simulation model is constructed. The historical compaction parameters are then used one by one for the simulated compaction in the model, and the corresponding historical settlement is used to train and optimize the model. In this way, by inputting historical data for multiple rounds of iterative training, the model can be continuously optimized so that the simulated compaction effect output by it gradually approaches the actual situation, so as to facilitate the subsequent use of the trained simulation model for compaction plan calculation, which can greatly reduce the prediction deviation caused by model errors.

[0014] Optionally, the rammer in the ramming model is provided with an inertial measurement unit, and the ramming parameters include acceleration, angular velocity and position coordinates of the rammer. The ramming plan for the target foundation is determined according to the ramming simulation model and the target settlement depth, including: obtaining the initial acceleration, angular acceleration and position coordinates of the rammer sent by the inertial measurement unit; inputting the target settlement depth and the initial acceleration, angular acceleration and position coordinates of the rammer into the ramming simulation model for simulation to obtain the total number of rammings and a sub-plan corresponding to each ramming, the sub-plan including ramming parameters and theoretical settlement depth after ramming the target foundation according to the ramming parameters; and generating the ramming plan for the target foundation based on each of the sub-plans.

[0015] By adopting the above technical solution and setting an inertial measurement device in the rammer of the simulation model, the real-time kinematic parameters of the rammer, including acceleration, angular velocity and spatial coordinate information, can be obtained. These precise initial kinematic parameters and the predetermined target settlement amount are used as inputs for dynamic simulation calculations, which can accurately simulate the entire ramming process from a given starting state to achieving the target settlement, and can quantitatively solve the total number of ramming times that meet the requirements and the specific parameters of each ramming.

[0016] Optionally, adjusting all subsequent sub-plans after the current sub-plan according to the settlement deviation value includes: determining whether the absolute value of the settlement deviation value is greater than a preset first deviation threshold; if the absolute value of the settlement deviation value is greater than the first deviation threshold, adjusting all subsequent sub-plans after the current sub-plan based on the settlement deviation value.

[0017] By adopting the above technical solution, the measured settlement of each tamping stage is compared with the corresponding theoretical value and the deviation is calculated. If the absolute value of the deviation exceeds the preset threshold, it means that the tamping effect of this stage is significantly different from the expected target, and all subsequent tamping plans starting from the current stage need to be adjusted accordingly. This will allow the subsequent tamping parameters to change appropriately to correct the previous deviation and return the compaction result to the expected target, so that the result obtained after the strong tamping treatment of the foundation is more in line with the expected target.

[0018] Optionally, adjusting all subsequent sub-plans after the current sub-plan according to the settlement deviation value includes: if the absolute value of the settlement deviation value is not greater than a first deviation threshold, determining whether there is a deviation sub-plan set before the current sub-plan in which the absolute value of the deviation value is not greater than the first deviation threshold for consecutive times exceeding a preset number of times; if the deviation sub-plan set exists, calculating the sum of the settlement deviation values ​​in the deviation sub-plan set to obtain a total settlement deviation value; if the total settlement deviation value is greater than a preset second deviation threshold, adjusting all subsequent sub-plans after the current sub-plan based on the total settlement deviation value.

[0019] By adopting the above technical solution, when the single-stage deviation is not large, it is not adjusted immediately, but it is determined whether there are multiple consecutive deviation sub-plans before it. When it exceeds the preset number of consecutive times, the sum of the deviations of these sub-plans is counted to obtain the total deviation. If the sum of the cumulative deviations is greater than the second deviation threshold, it is also necessary to adjust all subsequent tamping parameters starting from the current plan accordingly, so that the compaction result returns to the expected target, so that the result obtained after the strong compaction treatment of the foundation is more in line with the expected target.

[0020] Optionally, the method also includes: in the process of tamping according to the tamping plan, acquiring low-frequency vibration data of the target foundation in real time to obtain a vibration spectrum distribution diagram; determining the proportion of the amplitude energy of the low-frequency vibration data that is less than a preset low-frequency band in the vibration spectrum distribution diagram, and when the proportion is greater than the preset proportion, issuing a warning message.

[0021] By adopting the above technical solution, in the process of implementing the tamping plan, the low-frequency vibration data of the target foundation is obtained at the same time, and the spectrum analysis is performed. Since the low-frequency vibration will be enhanced when the foundation has problems, a threshold is set to monitor the proportion of low-frequency signal energy. When it exceeds the preset proportion, it indicates that the foundation is abnormal, such as loose or collapsed. Once a low-frequency abnormality is detected, an early warning message is immediately issued to suspend the tamping operation in time to avoid further deterioration. It also helps to adjust the tamping plan in advance or take other measures to correct the foundation problem.

[0022] In a second aspect of the present application, a system for monitoring the amount of strong compaction is provided, the system comprising:

[0023] A tamping plan acquisition module is used to acquire a tamping plan for a target foundation, wherein the tamping plan includes a plurality of sub-plans that are performed in a sequential order, each tamping corresponds to a sub-plan, and each sub-plan includes tamping parameters and a theoretical settlement depth after tamping the target foundation according to the tamping parameters;

[0024] A deviation value determination module, used to obtain the actual settlement depth after the target foundation is tamped according to the tamping parameters in the current sub-plan, and calculate the settlement deviation value between the actual settlement depth and the theoretical settlement depth corresponding to the current sub-plan;

[0025] A tamping plan adjustment module is used to adjust all subsequent sub-plans after the current sub-plan according to the settlement deviation value, and tamp the target foundation according to all the adjusted subsequent sub-plans.

[0026] In a third aspect of the present application, a computer storage medium is provided, wherein the computer storage medium stores a plurality of instructions, wherein the instructions are suitable for being loaded by a processor and executing the above method steps.

[0027] In a fourth aspect of the present application, an electronic device is provided, comprising: a processor and a memory; wherein the memory stores a computer program, and the computer program is suitable for being loaded by the processor and executing the above-mentioned method steps.

[0028] In summary, one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0029] 1. This application obtains a pre-made phased tamping plan for the target foundation, which includes the parameters of each tamping and the corresponding theoretical settlement. Then, during the actual construction process, the actual settlement of each tamping stage is monitored, and the settlement deviation value is calculated by comparing it with the theoretical value. If the settlement deviation value exceeds the allowable range, it means that the actual tamping effect is different from the expected one. At this time, all subsequent tamping sub-plans starting from the current stage are adjusted according to the settlement deviation value, so that the subsequent tamping sub-plans are appropriately changed to reduce the deviation between the actual tamping effect and the theoretical expectation. In this way, through closed-loop feedback control, the tamping plan can be continuously optimized, so that the result obtained after the strong tamping treatment of the foundation is more in line with the expected goal;

[0030] 2. This application compares the measured settlement of each tamping stage with the corresponding theoretical value and calculates the deviation. If the absolute value of the deviation exceeds the preset threshold, it means that the tamping effect of this stage is significantly different from the expected target, and all subsequent tamping plans starting from the current stage need to be adjusted accordingly, so that the subsequent tamping parameters can be appropriately changed to correct the previous deviation and return the tamping result to the expected target, so that the result obtained after the strong tamping treatment of the foundation is more in line with the expected target;

[0031] 3. In the process of implementing the tamping plan, this application simultaneously obtains the low-frequency vibration data of the target foundation and performs spectrum analysis. Since low-frequency vibration will be enhanced when there is a problem with the foundation, a threshold is set to monitor the proportion of low-frequency signal energy. When it exceeds the preset proportion, it indicates that the foundation is abnormal, such as looseness or collapse. Once a low-frequency abnormality is detected, an early warning message is immediately issued to suspend the tamping operation in time to avoid further deterioration. It also helps to adjust the tamping plan in advance or take other measures to correct the foundation problem. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Please refer to Figure 1 , a flow chart of a method for monitoring the amount of strong compaction and tamping is proposed. The method can be implemented by a computer program, a single-chip microcomputer, or run on a monitoring system for the amount of strong compaction and tamping. The computer program can be integrated into a computer device or run as an independent tool application. Specifically, the method includes steps 10 to 30, and the steps are as follows:

[0040] Step 10: Obtain a tamping plan for the target foundation, which includes a plurality of sub-plans that are performed in sequence. Each tamping corresponds to a sub-plan, and each sub-plan includes tamping parameters and a theoretical settlement depth after tamping the target foundation according to the tamping parameters.

[0041] Specifically, the target foundation refers to the foundation to be treated with strong compaction, that is, the construction object of strong compaction. The target foundation has certain soil parameters and stratum characteristics, and needs to be compacted to improve its bearing capacity and overall stability. The tamping plan refers to a detailed construction plan for the tamping process of the target foundation, which is composed of multiple sub-plans in sequence. Each sub-plan corresponds to a tamping, including specific tamping parameters and theoretical settlement calculated based on these parameters. The tamping parameters include information such as the hammer weight, lift height, and acceleration of the tamping hammer. The plan guides the tamping process to achieve the expected treatment of the foundation by scientifically predicting the tamping effect at each stage.

[0042] Based on the above embodiment, as an optional embodiment, the step of obtaining the tamping plan of the target foundation may further include the following steps:

[0043] Step 101: Obtain historical tamping information of the target foundation according to a preset plan.

[0044] Step 102: Obtain soil parameters of the target foundation and target settlement depth of tamping, and establish a tamping simulation model based on the soil parameters and historical tamping information.

[0045] Step 103: Determine a tamping plan for the target foundation according to the tamping simulation model and the target settlement depth.

[0046] Specifically, the preset plan refers to a tamping plan based on the history of the target foundation, and the historical tamping information refers to the tamping parameters of each tamping obtained according to the preset plan, and the tamping parameters of the foundation during past construction, such as hammer weight, drop height, acceleration and other data, as well as the corresponding measured actual settlement, are collected. At the same time, standardized tests are performed to determine the relevant mechanical properties of the foundation. Then, a calculation model of the foundation is initially established based on soil parameters, and historical data is repeatedly used as model input. Multiple rounds of simulation calculations are performed, and the calculation results are compared with the measured settlement, and the model is continuously optimized to improve the simulation accuracy. In this way, a tamping calculation model that accurately reflects the characteristics of the foundation is obtained through training. Then, engineers can determine the expected foundation settlement target value according to construction requirements, and input it together with the model as known conditions, run multiple simulation iterations, and obtain the required reasonable total number of tampings and the parameter combination of each tamping under the constraints of the current foundation conditions and settlement target values, forming a complete tamping plan composed of each sub-plan. According to this scientific and reliable tamping plan to guide construction, the treatment effect of the foundation can be accurately and effectively achieved.

[0047] Based on the above embodiment, as an optional embodiment, the step of obtaining the soil parameters of the target foundation and the target settlement depth of the tamping, and establishing the tamping simulation model based on the soil parameters and the historical tamping information may further include the following steps:

[0048] Step 1021: Establish a virtual foundation to be compacted according to soil parameters.

[0049] Step 1022: construct an initial tamping simulation model, simulate the tamping of the foundation to be tamped according to the historical tamping parameters corresponding to each historical tamping number on the initial tamping simulation model, and use the historical settlement depth after tamping the target foundation with each historical tamping parameter as the simulated settlement depth.

[0050] Step 1023: Use the historical tamping parameters corresponding to each historical tamping number and the corresponding simulated settlement depth as training samples to train the initial tamping simulation model to obtain a trained tamping simulation model.

[0051] Specifically, soil parameters such as shear strength and internal friction angle of the target foundation are collected, and a virtual foundation model to be rammed is established based on these soil parameters. Then, a reasonable calculation unit is set in the model, an initial calculation relationship is established, and an initial simulation model of ramming is formed. According to the existing ramming data of the foundation, including the hammer weight and acceleration parameters used each time, the foundation to be rammed is simulated and rammed, and the historical settlement depth after each historical ramming parameter rams the target foundation is used as the simulated settlement depth. These historical ramming parameters are input into the initial simulation model in sequence for operation calculation to obtain the simulated calculation settlement result each time, that is, the simulated settlement depth. The input parameters and the calculation results are used as training data, that is, the historical ramming parameters corresponding to each historical ramming number, and the corresponding simulated settlement depth are used as training samples. The initial ramming simulation model is trained using optimization algorithms such as gradient descent, and the parameters in the model are gradually corrected through multiple rounds of iterative training, so that the calculation results are closer and closer to the actual measured values. After repeated training, the output of the simulation model will be able to highly fit the actual situation and accurately reflect the ramming-settlement characteristics of the specific foundation. Thus, an optimized and reliable ramming simulation model is obtained. The simulation results of this model can accurately and reliably guide the formulation of ramming plan.

[0052] Based on the above embodiment, as an optional embodiment, the step of determining the tamping plan of the target foundation according to the tamping simulation model and the target settlement depth may further include the following steps:

[0053] Step 1031: Obtain the initial acceleration, angular acceleration and position coordinates of the rammer sent by the inertial measurement unit.

[0054] Step 1032: Input the target settlement depth and the initial acceleration, angular acceleration and position coordinates of the rammer into the ramming simulation model for simulation to obtain the total number of ramming times and a sub-plan corresponding to each ramming, the sub-plan including ramming parameters and the theoretical settlement depth after ramming the target foundation according to the ramming parameters.

[0055] Step 1032: Generate a tamping plan for the target foundation based on each sub-plan.

[0056] Specifically, an inertial measurement device, such as a gyroscope, an accelerometer, etc., is installed on the rammer in the tamping model to collect various motion data of the rammer in the process of rising and falling in real time, including acceleration, angular velocity, displacement information, etc. Before simulating the tamping plan, the initial motion parameters such as acceleration, angular acceleration and coordinate position of the rammer in the initial state collected by the inertial measurement unit are first obtained. The predetermined target settlement amount and the obtained initial motion parameters are input into the established tamping simulation model. The model simulates and calculates the entire rising and falling process. After multiple iterations, the number of tamping times and the parameters of each hit, such as tamping height, hammer weight, etc., required to achieve a given settlement target in the current initial state are determined. Each tamping and the corresponding tamping parameters are taken as a sub-plan, and each sub-plan includes tamping parameters and the theoretical settlement depth after tamping the target foundation according to the tamping parameters. All sub-plans are integrated, and the overall phased tamping plan under the specific conditions is generated according to the order of their tamping, and the calculation of the tamping plan is completed.

[0057] For example, a bridge abutment needs to be reinforced, and the design settlement target value is 40cm. The tamping plan can be divided into four stages. The first stage: use a 10-ton hammer, a lifting height of 2 meters, to carry out high-altitude kinetic compaction, a total of 75 tamping effects, and a predicted settlement of 15cm. The second stage: use a 15-ton hammer, a lifting height of 1.5 meters for weight rolling compaction, a total of 60 tamping effects, and a predicted settlement of 10cm. The third stage: use a 12-ton hammer, a lifting height of 1 meter for low-altitude stable compaction, a total of 50 tamping effects, and a predicted settlement of 8cm. The third stage: use a 12-ton hammer, a lifting height of 1 meter for low-altitude stable compaction, a total of 50 tamping effects, and a predicted settlement of 8cm. Carry out tamping in the order of the above four stages, using different tamping methods, and predict that a total design settlement target of 40cm will be achieved. Each tamping in each stage corresponds to a sub-plan. For example, there are 80 sub-plans in the first stage. The tamping parameters of each sub-plan are: 15-ton hammer, lifting height of 1.5 meters, etc.

[0058] Step 20: Obtain the actual settlement depth after the target foundation is rammed according to the ramming parameters in the current sub-plan, and calculate the settlement deviation value between the actual settlement depth and the theoretical settlement depth corresponding to the current sub-plan.

[0059] Specifically, after each round of tamping, a mobile measuring scale or laser distance measuring device is placed on the surface of the foundation to accurately measure the actual settlement depth of the foundation surface relative to the benchmark. The sub-plan corresponding to the round of tamping is retrieved, and the theoretical settlement depth corresponding to the tamping in the sub-plan is obtained. The actual settlement depth obtained by the measurement is compared with the theoretical settlement depth obtained according to the sub-plan, and the settlement deviation value between the actual settlement depth and the theoretical settlement depth corresponding to the current sub-plan is calculated. If the actual settlement depth matches the theoretical settlement depth, it means that the effect of this round of tamping is as expected; if there is an obvious deviation, the subsequent tamping plan needs to be adjusted according to the deviation.

[0060] For example, the current tamping is the first stage: a 10-ton hammer is used with a lifting height of 2 meters to perform high-altitude kinetic compaction, a total of 75 tamping actions, and a predicted settlement of 15 cm. The theoretical settlement value of each tamping in each sub-plan of the first stage is 5 cm. When performing the tamping of the first stage, the actual settlement depth of the target foundation is obtained each time, and the settlement deviation value can be obtained by subtracting the theoretical settlement value from the actual settlement value.

[0061] Step 30: Adjust all subsequent sub-plans after the current sub-plan according to the settlement deviation value, and tamp the target foundation according to all the adjusted subsequent sub-plans.

[0062] Specifically, when the calculated actual settlement of the current tamping sub-plan deviates from the theoretical settlement value, it means that the tamping effect of this sub-stage has not met expectations. At this time, it is necessary to adjust all subsequent tamping sub-plans after the current sub-plan accordingly according to the size of the deviation and the positive and negative direction. Specifically, if the actual settlement is less than the theoretical value, it means that the compaction is insufficient, and it is necessary to increase the hammer weight or the number of blows in the subsequent plan to increase the tamping intensity. Conversely, if the actual settlement is too large, it is necessary to reduce the subsequent hammer weight or the number of blows to control the tamping intensity. In order to reduce the deviation between the actual tamping effect and the theoretical expectation, the tamping plan can be continuously optimized through closed-loop feedback control, so that the results obtained after the strong tamping treatment of the foundation are more in line with the expected goals.

[0063] Based on the above embodiment, as an optional embodiment, the step of adjusting all subsequent sub-plans after the current sub-plan according to the settlement deviation value may further include the following steps:

[0064] Step 301: Determine whether the absolute value of the settlement deviation is greater than a preset first deviation threshold.

[0065] Step 302: If the absolute value of the settlement deviation value is greater than the first deviation threshold, all subsequent sub-plans after the current sub-plan are adjusted based on the settlement deviation value.

[0066] Specifically, after calculating the settlement deviation value between the actual settlement depth and the theoretical settlement depth corresponding to the current sub-plan, it is necessary to determine whether the absolute value of the settlement deviation value is greater than the preset first deviation threshold value, which can be 1cm, or can be set according to actual conditions. If the absolute value of the settlement deviation value is greater than the first deviation threshold value, it means that the deviation is large. Then determine whether the settlement deviation value is positive or negative. If it is positive, the actual deviation is larger, and if it is negative, the actual deviation is smaller. Determine the adjustment coefficient according to the deviation direction and size, and preferably take 50% of the deviation value as the adjustment range. If it is actually smaller, the number of hits of each subsequent sub-plan is increased proportionally. If the deviation is -5cm, the subsequent plan increases the number of hits by 2.5% (50%*5cm). In other feasible embodiments, the combination of various factors such as the number of hits, the weight of the hammer, the height of the rise and fall, and the acceleration of the shot-down can also be adjusted to achieve the adjustment of the subsequent sub-plan. Increase the hammer weight: If the hammer weight of the subsequent stage is increased by 10%, the tamping strength can be increased. Increase the take-off and landing height: such as increasing the height by 10-20%, enhancing the effect by increasing the hammering kinetic energy, etc.

[0067] For example, when the settlement deviation value is -2cm, which is greater than the allowable error of 1cm, since the actual tamping depth is too small, the number of subsequent tamping is increased by 50% of the deviation value, that is, the number of tamping is increased by 1% (2*50%=1cm). The second stage plans to have 80 hits, and an increase of 1% means an increase of 0.8 times, which is rounded to 1. The third stage plans to have 60 hits, and an increase of 1% means an increase of 0.6 times, which is rounded to 1.

[0068] Step 303: If the absolute value of the settlement deviation is not greater than the first deviation threshold, determine whether there is a deviation sub-plan set before the current sub-plan whose absolute value of the deviation is not greater than the first deviation threshold for consecutive times exceeding a preset number of times.

[0069] Step 304: If there is a deviation sub-plan set, the sum of the settlement deviation values ​​in the deviation sub-plan set is calculated to obtain a total settlement deviation value.

[0070] Step 305: If the total settlement deviation value is greater than a preset second deviation threshold, all subsequent sub-plans after the current sub-plan are adjusted based on the total settlement deviation value.

[0071] Specifically, when the absolute value of the settlement deviation value is not greater than the first deviation threshold, it means that the current tamping is more consistent with the expectation, and no adjustment is made temporarily. At this time, it is necessary to judge whether there are multiple continuous sub-plan deviations that are also within the allowable range, that is, whether there is a deviation sub-plan set whose absolute value of the deviation value that exceeds the preset number of times is not greater than the first deviation threshold before the current sub-plan, and the preset number of times can be five times, that is, after tamping according to the current sub-plan, it is judged whether there is a deviation sub-plan set whose absolute value of the deviation value is not greater than the first deviation threshold before the current sub-plan. If there are records of relatively small settlement deviations for example 5 times before the current sub-plan, these continuous settlement deviation values ​​are added one by one to obtain a cumulative total settlement deviation value. Then it is judged whether this cumulative total settlement deviation value exceeds the preset second deviation threshold, and the second deviation threshold can be 5cm in the embodiment of the present application. If the total settlement deviation value is greater than the preset second deviation threshold, it shows that although the single deviation is very small, the long-term cumulative aftereffect has greatly affected the overall compaction quality. Then, all sub-plans after the current plan can be adjusted accordingly according to the cumulative deviation value to compensate. The adjustment method is the same as the previous single deviation adjustment, which will not be repeated here. It can solve the problem of the impact of long-term accumulation of small deviations and ensure the compaction quality. For example, if the deviations of the previous five plans were 2cm, 1cm, 1.5cm, 0.5cm, and 1cm, respectively, and the cumulative total was 6cm, which exceeded the second deviation threshold of 5cm, then although the current plan has no significant difference, the subsequent sub-plans must be adjusted to correct the impact of the previous deviations.

[0072] Based on the above embodiment, as an optional embodiment, during the process of tamping according to the tamping plan, a process of detecting and warning the relevant information of the foundation is also included. The specific process is as follows:

[0073] Specifically, in the process of tamping according to the tamping plan, unexpected situations may occur due to different conditions of the foundation, such as local collapse of the foundation or decreased overall stability. Therefore, it is necessary to monitor the low-frequency vibration signal in real time on the target foundation. Specifically, a vibration sensor is set on the surface of the foundation to collect vibration acceleration or velocity signals in the vertical direction. A seismograph or MEMS accelerometer can be selected for detection, and then the collected vibration signal is fast Fourier transformed to obtain a vibration spectrum distribution diagram. The focus is on analyzing the proportion of the amplitude energy of the low-frequency vibration data less than the preset low-frequency band in the vibration spectrum distribution diagram, such as the energy size within the range of 0-10Hz. Among them, the enhancement of low-frequency vibration often indicates a foundation problem, so the preset proportion refers to 30% in the embodiment of the present application, and it is judged in real time whether the proportion exceeds the preset proportion. Once the preset proportion is exceeded, it can be determined that the foundation is abnormal, and there may be local loosening or collapse. At this time, an early warning is immediately triggered, and a signal is sent to suspend tamping to avoid further deterioration. At the same time, engineering and technical personnel need to check the foundation for maintenance and reinforcement. The tamping operation can be resumed after confirming that the problem has been solved. By monitoring and analyzing low-frequency anomalies, we can effectively prevent and control risks in complex compaction processes and ensure the quality of the foundation.
