酸雨对滑坡土体抗剪强度参数影响试验研究

Experimental study on impact from acid rain on parameter of shear strength of landslide soil body

以三峡库区酸雨对滑坡土体抗剪强度参数的影响为背景,阐述了国内特别是三峡库区酸雨特性,并配置一定pH值的盐酸溶液浸泡滑坡土体模拟酸雨对土体的作用,采用室内直接剪切试验,研究了饱和重塑滑坡体土体经历不同浸泡酸化时间的抗剪强度参数变化规律。

Based on the impact from acid rain on the on shear strength parameters of landslide soil body within the area of Three Gorges Reservoir, the characteristics of acid rain in China, especially the acid rain within the area of Three Gorges Reservoir is described herein, and then a laboratory direct shear test is made on the landslide soil soaked with the hydrochloric acid solution of a certain pH value to simulate the impact from acid rain on the soil body; with which the law of the variation of the shear strength parameter of the saturated-remodeled landslide soil body soaked through different acidifying periods is finally studied .
