摘　　要：泽江小区滑坡位于湖南省湘乡市湘乡水泥厂生活区,为小型推移式土质滑坡。本文通过资料收集、野外调查、工程地质钻探和岩土试验等手段,分析了滑坡区的地质环境、滑坡特征及成因机制,并进行了滑坡稳定性计算和评价。稳定性计算结果表明,泽江小区滑坡在天然工况下暂处于欠稳定—基本稳定状态,但在暴雨工况下处于不稳定状态。计算结果与灾害体现场实际定性判断基本吻合。研究结果可为进一步的工程治理提供依据。Located in the residential area of Xiangxiang Cement Factory in Xiangxiang City,Hunan Province.The landslide at Zejiang Community is a small translational soil landslide.By means of data collection,field investigation,engineering geological drilling,and geotechnical test,this study analyzed the geological environment,characteristics and genesis mechanism of landslide,and landslide stability was calculated and evaluated.The stability calculation results showed that the landslide at Zejiang Community is in a state of slight instability to basically stable in the natural state,but become unstable during heavy rainfall.The calculated results are basically consistent with qualitative on⁃site assessment of the disaster.The research results provided a basis for further engineering management.
