AI Technical Summary

Technical Problem

Existing technologies for slope reinforcement suffer from insufficient precision in adjusting the output of the hydraulic station for anchor tensioning and controlling the pressure of the grouting machine. This makes it difficult to adapt to the mechanical properties of different soil and rock layers, resulting in uneven distribution of anchor prestress, which may lead to local stress concentration or anchorage failure, thus affecting slope stability.

Method used

A three-dimensional deformation monitoring dataset is constructed by combining a distributed fiber optic sensing system with a spaceborne interferometric synthetic aperture radar. The three-dimensional stress field is inverted using an LSTM-soil constitutive model, and the parameters of shear modulus degradation rate, creep coefficient, and displacement increment prediction are output. This generates control strategies for the anchor tension gradient and grouting pressure range.

Benefits of technology

It enables multi-scale, all-round slope monitoring, improves the accuracy and timeliness of stability analysis, and allows for timely and precise intervention for potential risks, reducing the probability of geological disasters such as landslides and protecting life and property.
