以云南省新平县境内哀牢山中段一滑坡隐患点为研究对象,用SLOPE/W软件建立物理模型,就含水率和坡度对坡体稳定性的影响进行了综合分析.用MATLAB进行数值计算,得出含水率、坡度与边坡稳定系数的影响曲线.将坡度在28~33°间的区域设为重点监测对象,并设定含水率21%为预警阈值,含水率23%为警报阈值.为该地域多指标预警工作提供了一定的参考.
Taking the hidden spots of a landslide in the middle section of Ailao Mountain in Xinping County of Yunnan Province as the research object, the physical model was established by SLOPE / W software and the influence of moisture content and slope on the stability of the slope was comprehensively analyzed.The numerical calculation was carried out by MATLAB, The influence curve of moisture content, slope and slope stability coefficient is obtained, and the area with the slope of 28 ~ 33 ° is set as the key monitoring object, and the water content of 21% is the prewarning threshold and the water content of 23% is the alarm threshold. It provides a reference for multi-index early-warning work in this area.
