摘要： 通过野外勘查和地质钻探等手段对嘉陵江上游燕子河流域滑坡灾害进行了系统调查。从滑坡的分布、形态、结构及物质组成等方面研究滑坡灾害发育特征，并对典型滑坡（孙家院三社滑坡）稳定性进行了定量分析，分别计算了天然暴雨及地震等不同工况条件下的滑坡稳定性。查明了滑坡灾害的分布特征、边坡形态、结构与物质组成。计算表明，暴雨条件下，滑坡不稳定，具有下滑的可能性。调查结果为该区滑坡灾害的预防和治理提供了科学依据。

Abstract: The landslide hazards of the Yanzi River Basin were systematically investigated by the field reconnaissance and geological drilling methods. The development characteristics of these landslides were evaluated from the locations of the occurrence, morphology, the landslide structure and material components aspects. The stability evaluation was performed at a typical landslide (Third Community of Dujiayuan Slide) under the normal condition as well as the extreme conditions, such as heavy rains and earthquake. The results indicate that, under the heavy precipitation condition, the slope is not stability and the potential slide might occur.
