摘要

在建立边坡远程实时监测系统并获得变形与降雨量连续监测数据的基础上

运用加卸载响应比理论的基本原理

提出以一用为加卸载周期、将日降雨量及其变化作为边坡的加卸载参数、相应的日平均变形速率及其变化值为加卸载响应参数

建立了基于加卸栽响应比的降雨型滑坡短周期预警模型。以某公路边坡为例

运用加卸载响应比预测模型对边坡的2个监测点进行了加卸载响应比计算

发现2个点的加卸载响应比时序曲线与其稳定性动态演化规律相吻合。研究结果表明

可以运用该模型进行降雨型滑坡短周期预测预警。

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.
