摘要
库水位波动和降雨是诱发三峡库区碎石土滑坡失稳的最重要的因素,库水位波动和降雨都是通过影响碎石土滑坡地下水赋存条件对碎石土滑坡产生作用的,将地下水对三峡库区碎石土滑坡的影响分为地下水对滑带土的物理化学作用使其强度减低、地下水对滑体的渗透力、地下水对滑体的浮托力作用三种作用,利用数学解析方法分析了上述三种作用对三峡库区碎石土滑坡的影响程度。
Reservoir water level fluctuation and rainfall are the most important factors inducing the instability of gravel soil landslide in the Three Gorges reservoir area. The reservoir water level fluctuation and rainfall all affect the gravel soil landslide by affecting the groundwater occurrence conditions of the gravel soil landslide. In this paper, the influence of groundwater on the landslide of the Three Gorges reservoir area is divided into three types： the physical and chemical effects of groundwater on the slip zone soil, the strength reduction, the penetration of groundwater on the landslide, and the effect of groundwater on the floating force of the landslide. The mathematical analysis method is used to analyze the influence of the above three effects on the landslide of the Three Gorges reservoir area.
