詹家湾滑坡为一土质推移—牵引式滑坡,并且以推移作用为主,目前滑坡处于蠕动阶段,但在大气降雨,河流水位的变化,河流的侵蚀和人类工程活动的共同影响和作用下,滑坡变形有加剧的趋势。本文叙述了三峡库区詹家湾滑坡的工程地质条件,分折了滑坡成因机理,在此基础上提出了滑坡防治方案:抗滑桩+排水沟。
Zhanjiawan landslide is a soil-moving traction-type landslide, and is dominated by the thrusting effect. At present, the landslide is in the creeping stage. However, under the common influence of atmospheric rainfall, changes in river water level, river erosion and human engineering activities, Landslide deformation has aggravated trend. This paper describes the engineering geological conditions of the Zhanjiawan landslide in the Three Gorges Reservoir Area and analyzes the mechanism of landslide formation. Based on this, the landslide prevention and control program is proposed: anti-slide pile + drainage ditch.
