三峡工程库岸重点滑坡稳定性监测及分析

Stability Monitoring and Analyses of Key Landslides on Reservoir Bank of Three Gorges Project

本文首先概述了60年代以来对长江三峡工程库岸滑坡稳定性作过的大量监测和分析工作。包括现场岩石抗剪强度、位移、应力试验和监测;稳定性计算分析、位移反分析和卫星遥测技术应用的研究等。然后着重介绍了黄腊石滑坡的深部位移监测以及在1991年渡汛期间所起的重要作用。简述了新滩滑坡位移反分析的方法、稳定性评价和它在发展位移反分析方法上的意义。

In this paper, a large quantity of monitoring and analyses on landslides of reservoir bank of Three Gorges Project at Yangtze River since 60's are summarized at first, which included in-situ tests and monitoring (such as shear strength, displacement and stresses) , stability calculation, back analyses of displacement and application of remote-measuring technology by satellite. Then the deep displacement monitoring of Huanglashi landslide and it's important role played during the flooding season in 1991 are emphatically introduced. Finally, the method of back analyses of displacement on Xintan landslide and it' s great role in developing, the methodology of back analyses of displacement are briefly stated.
