塘角村1号滑坡是三峡库区地质灾害防治监测预警工程Ⅲ期应急专业监测点.监测方法为滑体深部位移监测、地表位移监测等.本文通过滑坡变形、库区降雨、库区水位变化等资料的相关分析,总结分析了该滑坡在窄间和时间域内的变形特征.降雨强度和降雨量的大小是影响滑体变形速率的因素之一,下部滑体变形对于库区水位下降敏感,当水位在一段时期内按一定速率持续下降时,滑体变形速率明显加大.

The No. 1 landslide of Tangjiao Village is a professional inspecting spot for the third early warning project of geological hazards inspecting in the Three Gorges Reservoir area. The inspecting methods include surface displacement monitoring and subsurface displacement monitoring, etc. The landslide had an abvious deformation during drawdown of reservoir stage with a wide range in April, 2007. Based on correlation analysis of deformation, reservoir stage and precipitation, this paper generalizes the characteristics of the landslide in space and time domain. The rainfall and intensity is one of the influencing factors for deformation of the landslide. The lower body is sensitive to drawdown of reservoir stage. The velocity of displacement enlarges evidently because the continue drawdown with velocity band in a time.
