【摘要】 讨论了最近5年以来贵阳市发生的重大滑坡事件以及人工斜坡的稳定问题。从中可以看出碳酸盐岩斜坡稳定性评价中的一些特殊问题。例如由于溶蚀和岩溶地下水的作用可形成隐蔽的滑移面,溶蚀裂隙形成滑坡拉裂面和切割面以及形成可塑—软塑的泥化夹层等。经验表明,没有及时防护的顺向坡坡脚开挖是造成贵阳市滑坡的主要原因。更多还原

【Abstract】 The events of landslide and the problems of stability of artificial slopes in Guiyang City since recent 5 years were discussed.Some special problems of stability evaluation of carbonate rock slopes can be seen from this paper.For example,the plastic-soft plastic argillization interbed and the concealed slip plane can be formed by the process of karst dissolution and karst groundwater which also can dissolute the fissure of rocks to form pull-apart planes and dissection surfaces in slope,and so on.The experiences indicate that the excavation of consequent slope’s foot without support on time is the major reason provoking the landslides in Guiyang City.更多还原
