摘　　要：在阐明咸德坪子滑坡地质环境背景的基础上,分析影响滑坡孕育发生的各种因素,探讨滑坡形成过程,指出降雨是影响滑坡孕育形成过程中最重要的因素之一,尤其地下水对滑面的形成起到了至关重要的作用,不同暴雨强度条件下滑坡稳定性验算结果也证明了这一点。进一步的分析表明,滑坡未来仍然存在发生次级滑动的可能。该滑坡形成过程中,地下水动态变化明显,并有泉出露,是一个较有研究价值的实例。This paper base on the engineering geological environmental background of Xian De Ping Zi landslide,analyze the main influence factors that cause the land slide, then discuss the process of landslide forming , point out that the rainfall is one of the most important factors during the process of landslide forming. What＇ s more the groundwater play an important part during the process of sliding sur face forming. The results of landslide stability calculation in different rainstorm conditions can prove this conclusion. According to the indepth analysis, the landslide may occur secondary landslide in future. During the process of landslide forming, groundwater dynamic change significantly , for example three springs are formed on the slip mass , so the landslide has the research value.
