Especially in complex terrain areas such as mountain roads, risk management of deep foundation pits and high slopes has become particularly important. These engineering constructions not only face uncertainties during the construction process, but are also affected by factors such as climate change, geological conditions and external environment.

[0065] Example 2
[0066] This example is an explanation of Example 1. Figure 1 ,Specifically, step one includes:
[0067] S11. Use GIS technology and related surveying and mapping data to obtain electronic distribution maps of deep foundation pits and high slopes on mountain roads;
[0068] The deep foundation pit and high slope area of mountain highway are divided into several monitoring areas, and several monitoring areas are marked on the electronic distribution map of deep foundation pit and high slope of mountain highway as: Jcq1, Jcq2, ..., Jcq n ; n represents the number of monitoring areas;

[0070] In this embodiment, by using GIS geographic information system technology to construct an electronic distribution map of deep foundation pits and high slopes of mountain roads, accurate division of complex terrain can be achieved. Dividing the monitoring area into multiple specific areas can make the risk data of each monitoring area more refined and independent, avoiding the problem of inaccurate or missed monitoring data due to the wide range of areas in traditional monitoring methods, thereby improving the overall monitoring efficiency and accuracy. This method not only collects geological data on the compressive strength of rock and soil layers, soil hardness, thickness and water content, but also combines meteorological data on rainfall, groundwater pressure, permeability and structural data on the bearing capacity and load value of supporting structures.

[0071] Example 3
[0072] This example is explained in Example 2. Figure 1 ,Specifically, step 2 includes:
[0073] S21. Using the data from the first data set, monitor the geological conditions of the deep foundation pit height and slope. After dimensionless processing, calculate and obtain the geological stability coefficient DZxs of the i-th monitoring area. i , the formula is as follows:
[0074]
[0075] Where n i represents the number of rock and soil layers in the i-th monitoring area, σ cj,i represents the compressive strength of the jth rock and soil layer in the i-th monitoring area, σ max Indicates the maximum compressive strength of the rock and soil layer, H j,i represents the hardness of the j-th rock layer in the i-th monitoring area, d j,i represents the thickness of the jth rock and soil layer in the ith monitoring area, w j,i It represents the moisture content of the jth rock and soil layer in the i-th monitoring area, k1 represents the influence coefficient of soil moisture content, k2 represents the influence coefficient of soil pressure, k1 and k2 are obtained through experimental data, and the commonly used values are as follows:
[0076]
[0077]
[0078] In this embodiment, by comprehensively considering multiple geological indicators such as the compressive strength, hardness, thickness, and soil moisture content of the rock and soil layer, the calculated geological stability coefficient can fully reflect the geological stability of each monitoring area. This method can effectively identify potential risk areas and predict possible slope landslides or foundation pit collapses in advance. Accurately calculating the influence coefficients of soil moisture content and soil pressure based on experimental data can enable the monitoring system to take into account complex changes in soil conditions. The influence coefficients for different moisture content intervals and pressure ranges can ensure that the monitoring results under different environments are more accurate, providing a reliable scientific basis for engineering decision-making.

[0084] In this embodiment, based on the calculation of the geological stability coefficient and the comparative analysis with the pre-set threshold, the stability of the monitoring area can be evaluated, thereby providing scientific guidance for resource allocation and protective measures during the construction process. For areas with poor stability, early warning signals can be issued, and reinforcement support or precipitation measures can be increased to ensure the safety of personnel and equipment during the construction process.
[0085] Example 5
[0086] This example is an explanation of Example 1. Figure 1 ,Specifically, step three includes:

[0092] In this embodiment, the real-time meteorological environment data can reflect the impact of the current meteorological environment on geological stability in real time. When it is found that abnormal weather causes the groundwater level to rise or the groundwater flow to increase, the groundwater inrush index is calculated, which can accurately reflect the impact of groundwater on the stability of deep foundation pits and high slope areas. The system can issue warnings in time and identify potential risk areas of geological instability in advance, so as to take necessary protective measures to avoid accidents.

[0096] When the groundwater inrush index QXxs in the i-th monitoring area i When it is less than or equal to the second standard threshold value K, it means that there is no risk of geological instability in the current monitoring area. There is no risk of formation of infiltration channels in the geological area, which may induce water inrush risk, and continuous monitoring is required;
[0097] When the groundwater inrush index QXxs in the i-th monitoring area i >the second standard threshold value K, it indicates that there is a risk of geological instability in the current monitoring area and there is a risk of formation of a seepage channel in the geological area, inducing a risk of water inrush, triggering the second early warning instruction and generating a second risk signal.
[0098] In this embodiment, by comparing and analyzing the threshold value set in advance with the groundwater inrush index, specific risk values can be provided to on-site engineers and decision makers, which can directly affect the formulation of emergency measures. When the groundwater pressure or permeability value reaches a critical value, an early warning signal is issued.

[0102]
[0103] In the formula, n represents the number of monitoring areas, represents the bearing capacity of the deep foundation pit support structure in the ith monitoring area, DZxs i represents the geological stability coefficient of the ith monitoring area, QXxs i represents the groundwater inrush index of the ith monitoring area, represents the load factor of the deep foundation pit in the ith monitoring area, represents the load value of the deep foundation pit building in the i-th monitoring area, A i represents the area of the deep foundation pit in the ith monitoring area;
[0104]
[0105] In the formula, represents the shear strength of the high slope soil in the ith monitoring area, Hg i represents the height of the high slope in the ith monitoring area, θ i represents the angle of the high slope in the ith monitoring area, represents the load factor of the high slope in the ith monitoring area, represents the load value of the ith monitoring area and the high slope, Ag i Represents the bottom area of the high slope in the i-th monitoring area.
[0106] In this embodiment, the real-time data of the monitoring area is comprehensively analyzed and dimensionlessly processed to calculate the risk coefficient of deep foundation pit collapse and the risk coefficient of inclination deformation of high slopes. This method is more comprehensive than traditional single factor analysis and can comprehensively evaluate potential risks under complex geological and environmental conditions, thereby improving the accuracy of risk prediction.
[0107] Example 8
[0108] This example is an explanation of Example 1. Figure 1 Specifically, step four also includes:
[0109] S42, pre-set the third standard threshold Z1, and calculate the deep foundation pit collapse risk coefficient Sfx of the i-th monitoring area. i A comparison and evaluation is performed with the third standard threshold value Z1 to obtain a third evaluation result, including:
[0110] When the deep foundation pit collapse risk factor Sfx in the i-th monitoring area i When the value is less than the third standard threshold Z1, it means that there is no risk of collapse of the deep foundation pit and continuous monitoring is required;
[0111] When the deep foundation pit collapse risk factor Sfx in the i-th monitoring area i When it is ≥ the third standard threshold Z1, it indicates that the deep foundation pit is at risk of collapse, triggering the third warning instruction and generating the first strategy, including: increasing the compressive strength of the soil around the foundation pit by 10% and the soil layer stability by 20% through deep mixing method; reinforcing the loose soil layer through grouting technology and increasing the soil bearing capacity by 30%; building temporary shielding facilities and setting up 2 drainage points to reduce the impact of precipitation on the foundation pit by 70%.
[0112] In this embodiment, by setting a standard threshold Z1 and comparing and evaluating it with the risk factor, the system can issue an early warning in time when the risk of a deep foundation pit exceeds the set threshold. This early warning mechanism has an efficient response capability, can identify potential risks in advance, avoid sudden disasters, and ensure the safety of construction personnel and projects. When the risk factor reaches the early warning standard, the system can automatically generate the first strategy and propose targeted reinforcement and protection measures, such as deep mixing method, grouting technology, and the construction of temporary shielding facilities. These measures help to directly improve the compressive strength, bearing capacity and stability of the soil, reduce the probability of foundation pit collapse, and effectively reduce safety hazards in construction.
[0113] Example 9
[0114] This example is an explanation of Example 1. Figure 1 Specifically, step four also includes:
[0115] S43, pre-set the fourth standard threshold Z2, and calculate the inclination deformation risk coefficient Gfx of the high slope in the i-th monitoring area. i A comparison and evaluation is performed with the fourth standard threshold value Z2 to obtain a fourth evaluation result, including:
[0116] When the high slope deformation risk factor Gfx in the i-th monitoring area i < the fourth standard threshold Z2, indicating that the high slope has no risk of tilt deformation and continuous monitoring is required;
[0117] When the high slope deformation risk factor Gfx in the i-th monitoring area iWhen it is ≥ the fourth standard threshold value Z2, it indicates that the high slope is at risk of tilting and deformation, triggering the fourth warning instruction and generating the second strategy, including: reinforcing and improving the bearing capacity of the deep foundation pit retaining wall by 20%, increasing the anchor density by 25% and improving the strength of the reinforced concrete retaining wall by 10%; reducing water accumulation by 40% and reducing the water penetration pressure on the soil by 25% by setting 2 drainage points; strengthening the bearing capacity of the loose soil through shotcrete technology and increasing the tensile strength of the soil by 35%.
[0118] In this embodiment, by presetting the standard threshold value Z2 and comparing it with the tilt deformation risk coefficient, the system can promptly identify the tilt deformation risk of high slopes. Once the risk coefficient exceeds the set threshold, the system will automatically trigger the early warning mechanism to effectively prevent potential landslides or tilt deformation accidents, and provide advance warnings for construction and the surrounding environment. When the risk coefficient exceeds the standard threshold, the system will generate a second strategy, including targeted protective measures such as strengthening the deep foundation pit support wall, increasing the density of anchor rods, and improving the strength of retaining walls. These measures can effectively enhance the compressive resistance of the soil, improve the bearing capacity of the support structure, and reduce the accumulation and seepage pressure of water, thereby reducing the possibility of slope tilt deformation.

The trained risk dynamic early warning model is used as data for running prediction to perform real-time risk prediction of deep foundation pits and high slopes of mountain roads.
[0122] In this embodiment, by establishing a convolutional neural network model, risks can be dynamically monitored and predicted in real time. Combined with real-time acquisition of feature information and training, the early warning model is continuously optimized to improve prediction accuracy, reduce reliance on manual intervention, and ensure the automation and efficiency of risk management. Through systematic risk assessment and early warning measures, the safety management level of engineering projects is improved, and data support and reference basis are provided for subsequent engineering maintenance and upgrades, which has strong sustainability.
