摘要
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。
According to the characteristics of geological hazards in head region of Three Gorges Reservoir, a certain landslide in Zigui City is chosen to study its deformation characteristics by using the data of rainfall, water level and dis- placement monitoring with GPS in recent years. And then the influence of the rainfall and reservoir water level on deform- ation of landslide is analyzed. The results show that it is a lapsed landslide from the displacement curves; the horizontal accumulated displacement curve has characteristics of periodic step shape, which is greatly influenced by rainfall and res- ervoir water level; especially, it is more influenced by joint action of theses two factors.
