摘要

三峡库区滑坡的失稳，主要是水库水位的升降、大气降雨和人类活动等因素的影响引起的，滑坡的滑带土在水的反复浸泡作用下，其强度降低是导致大量古滑坡复活或产生新生型滑坡的主要原因。通过对千将坪滑坡滑带土在干―湿循环试验（DWC）条件下与天然非饱和土CU试验结果比较，研究了干-湿循环条件下滑坡滑带土强度特性及其变形特性，揭示了千将坪滑坡失稳机制。

Abstract

For the instability landslide in the Three Gorges Reservoir region

the change of the reservoir water level

atmospheric precipitation and other factors arising from the impact of human activities will be the chief reasons. Landslide sliding zone which repeatedly immersed in water under its intensity is a large number of ancient landslide or produce new landslide in the region. Based on the slide belt Qianjiangping landslide in wet-dry cycle test (DWC) and the consolidated-undrained triaxial test (CU) of unsaturated soil under natural conditions results

studied wet-dry cycle Qianjiangping landslide conditions slippery soil strength and deformation characteristics

reveals the instability mechanism of Qianjiangping landslide.
