江西兴国水沟村滑坡特征、成因及稳定性分析

Analysis of landslide characteristics,causes and stability in Shuigou village,Xingguo county,Jiangxi province

采用定性与定量相结合的分析方法进行研究,定性分析了水沟村滑坡的形成条件、发育特点等,定量分析了其稳定性。研究结果表明:水沟村滑坡为小型牵引式土质滑坡,其形成受岩土性质、降雨因素及人为因素三者共同影响;通过对滑坡进行定量分析可知,在自重工况下滑坡稳定系数为1.83(>1.15),整体处于稳定状态;在自重+暴雨工况下滑坡稳定系数为1.03,斜坡处于欠稳定状态,故可能在暴雨冲刷下再次发生滑坡。研究成果对认识和研究此类滑坡具有重要的科学意义,可以为今后指导防灾和减灾提供参考。

In this paper,qualitative and quantitative analysis methods were combined to analyze the formation conditions and development characteristics of Shuigou village landslide,and its stability was quantitatively analyzed. The research indicated that the Shuigou Village landslide was a small traction type soil landslide,and its formation was affected by the geotechnical properties,rainfall factors and human factors.Through the quantitative analysis of the landslide,the stability coefficient of the landslide under self-weight conditions was 1.83(>1.15),the whole was in a stable state;in the self-weight+ heavy rain conditions,the slope stability coefficient was 1.03,and the slope was in an unstable state,hence the landslide may occur again under the storm.Through the research results of this paper,it has important scientific significance for understanding and studying such landslides,and provides reference for guiding disaster prevention and disaster reduction in the future.
