针对库区地质灾害的特点,以三峡库首区秭归县某滑坡为例,基于近年来GPS位移监测、库区降雨与水位变化资料,分析了滑坡的变形特征,并研究了降雨与库水位变化因素对滑坡变形的影响。结果表明,该滑坡变形区呈推动式变形特征,其水平累积位移曲线具周期性台阶状位移特征,且受降雨和库水位变化影响较大,两者联合作用影响更大。
Aiming at the characteristics of reservoir geological disasters, taking a landslide in Zigui County of the Three Gorges Reservoir as an example, based on GPS displacement monitoring, rainfall and water level changes in the reservoir area in recent years, the deformation characteristics of the landslide are analyzed, and the changes of rainfall and reservoir water level Influence of Factors on Landslide Deformation. The results show that the deformation zone of the landslide is in the form of a pusher deformation, and the horizontal cumulative displacement curve has the characteristics of periodic step-like displacement and is greatly influenced by the changes of rainfall and the reservoir water level. The combined effect of the two effects is greater.
