基于加卸载响应比理论的降雨型滑坡预警研究
Research on Early Warning of Rainfall-induced Landslides Based on Load-unload Response Ratio Theory
摘要
Abstract
Based on the real-time remote monitoring system of slope, this paper proposes that the daily rainfall and its change can be selected as the loading-unloading dynamical parameter and the average deformation velocity and its change as the dynamical response parameter to establish the short cycle pre-warning model of rainfall-induced landslides. The calculation of loading-unloading response ratio of monitoring points of a mountain highway slope is completed by using the loading-unloading response prediction model. The computation results show that the curves of loading-unloading response ratio of monitoring points agree with the dynamic evolution law of the slope stability. All the above-mentioned results show that the daily rainfall dynamic model of the loading-unloading response ratio can be used to perform the short cycle early warning of the rainfall-induced landslides.关键词
