摘要

在系统分析堆积层滑坡的物质组成和失稳动因的基础上，运用加卸载响应比理论的基本原理，首次提出了将月降雨量及其变化作为该滑坡的加卸载参数，相应月平均位移速率及其变化值为加卸载响应参数，由此所确定的位移加卸载响应比作为堆积层滑坡的位移动力学参数。并根据三峡库区降雨量与堆积层边坡位移相关关系论证了应用该位移动力学参数评价堆积层边坡稳定性的可行性和有效性。最后，运用加卸载响应比动力学参数对三峡库区黄腊石滑坡排水工程实施前后的稳定性进行了评价，评价结果与该边坡排水工程前后的稳定性变化相吻合。这表明了加卸载响应比位移动力学参数是堆积层边坡稳定性评价的一种有效位移动力学参数，可以运用该位移动力学参数对该类边坡的稳定性进行评价与预测。

Abstract

Based on systematic analysis of the composition and mechanism of the debris landslides

this paper first proposes that the monthly rainfall and its change can be selected as the load-unload dynamical parameter

the average displacement velocity and its changes as the dynamical response parameter to load-unload and the displacement load-unload response ratio as the displacement dynamics parameter of debris landslide induced by water in term of the principle of the load-unload response ratio theory. Meanwhile

on the basis of analysis of the data of the displacement and rainfall of the debris landslides in the Three Gorges Reservoirs area

the feasibility and effectiveness of the displacement dynamics parameter are discussed. Finally

the stability of Huanglashi slope in the Three Gorges area before and after the water drainage are evaluated respectively by means of the dynamical parameter of the load-unload response ratio; and the evaluated results are well agreed with the practical stability situation of the slope. Therefore

all results above show that the dynamical parameter of load-unload response ratio proposed is a very effective displacement dynamical parameter in the stability evaluation of debris slopes; and it can be used in the evaluation of the stability of debris landslides induced by water.
