| 摘 要： | 文章以黄腊石滑坡群中的两个相邻滑坡(大石板滑坡和石榴树包滑坡)为例,研究了水在这两个滑坡产生过程中的作用,结论为:长江水位的抬升一方面抬高了滑体中的地下水位,另一方面使石榴树包滑坡约1/3的滑体浸泡在江水中,造成其发生多次滑塌;降水一方面引发坡面泥石流,另一方面使滑体的地下水位出现变化,增加滑体重量,软化滑带;地下水的静水压力和动水压力是促使大石板滑坡产生变形的主要影响因素,却是石榴树包滑坡变形的次要影响因素,地下水在石榴树包滑坡变形中的作用主要表现为软化滑带、降低滑带的抗剪强度。

| Abstract: | Water plays an important role in landslide deformation.Affection of water is always different in different process of landslide deformations.Even in the same landslide group,water also has different functions in different landslide deformation.The function can be list as: raising the weight of the landslide body;softening the sliding zone;bringing the static hydraulic pressure,dynamic hydraulic pressure and buoyancy;lessening the anti-shear strength;and reinforcing the slid force.Taking the two adjacent landslides(the Dashiban and Shiliushubao landslides) in the Huanglashi landslide group as an example,the functions of groundwater are examined.The results indicate that hydrostatic and hydraulic pressures are the main factors causing the Dashiban landslide to go steadily downhill and are the minor factors producing the Shiliushubao landslide.The role of groundwater in the Shiliushubao landslide includes softening the smooth belt and reducing the shear strength of the smooth belt. |
