摘　　要：通过野外勘察及室内外试验整理，从定量与定性两个方面对滑坡体的稳定性进行计算分析，表明根达坎土料场滑坡体目前总体上在天然状态处于基本稳定～欠稳定状态，在不利工况条件下（切坡、暴雨、暴雨＋地震状态），极易发生局部失稳或整体性失稳，建议在对土料进行开采时，采取自上而下、放坡分层开挖，严禁先挖坡脚的危险作业。In accordance with field investigation and indoor-outside experiments, calculation and analysis on stability of landslide from two aspects as quantitative and qualitative, it demonstrates that the landslide of Gendakan soil borrow area is in basically- under stable status in unfavorable engineering condition （slop cutting, downfall, downfall＋ earthquake）, It is easy to slip partially or roundly. So, suggestions are given to quarry earth -materials from upper layer to lower one. It is prohibited to excavate bottom of slope on earlier time.
