Monitoring point selection method and system for slope risk monitoring

Abstract

The invention belongs to the technical field of slope monitoring, and in particular relates to a monitoring point selection method and system for slope risk monitoring. The system includes a terrain acquisition unit, a simulation unit, an input unit, an analysis unit and a real-time acquisition unit; It is used to collect slope terrain data; the simulation unit is used for BIM modeling according to the collected slope terrain data to obtain a slope model; the input unit is used to input the survey data of the slope; the survey data includes geological survey data, geophysical data, drilling data and surveying and mapping data; the simulation unit is also used to combine the entered survey data with the slope model to obtain a simulation model; the analysis unit is used to perform point analysis on the simulation model to obtain monitoring points; the real-time acquisition unit is used to collect monitoring points The real-time data of the slope is obtained; the analysis unit is also used to analyze whether to update the monitoring point position according to the real-time data of the slope and the simulation model. The present application can select suitable slope monitoring points.

Description

technical field [0001] The invention belongs to the technical field of slope monitoring, and in particular relates to a monitoring point selection method and system for slope risk monitoring. Background technique [0002] Slope refers to a slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. Once a slope accident occurs, the loss of human and material resources will be huge. Therefore, it is necessary to monitor the state of the slope. [0003] The mainstream slope monitoring technology mainly obtains the displacement and earth pressure at the monitoring points on the slope through the arrangement and various sensors and mechanical facilities, and infers the slope state by changing the corresponding parameters. Since the consequences of slope risk are very serious, in order to ensure the validity of the monitoring results, the selection of monitoring points is very important. [0004] At present, monitoring points are often ...

AI Technical Summary

Problems solved by technology

[0004] At present, the monitoring points are often arranged only based on experience, resulting in many unreasonable monitoring point layouts, which waste manpower and material resources. The data collected by such monitoring points often cannot reflect the real situation of the slope where there are hidden safety hazards. For Slope risk monitoring is difficult to play its due role
