The influence of Reservoir Level Plummeting on Slope Stability Reinforced by Pile Jianqing Jiang1 a, Guoshao Su1, b, Liubin Yan1, c, Lei Ding1 d 1 School of Civil and Architecture Engineering, Key Laboratory of Disaster Prevention and Structural Safety, Guangxi University, Nanning, Guangxi, 530004, China a330694106@qq.com, bsuguoshao@163.com, cyanliubin@126.com, ddinglei1986qq@163.com Keywords: Slope, Reservoir, Pile, Reinforcement, Strength Reduction Method.
At present, anti-slide pile has been used widely in slope engineering.
It is the too much simplified calculation model, parameter selection of arbitrary and reliance on the engineering experience that will cause potential security and waste [2].
Moreover, the position of anti-slide pile have great impacts on slope reinforced effect, we should pay enough attention to the position of anti-slide pile in slope reinforcement engineering.
