根据实地调查,涉县西达镇河口村西小型滑坡对河口村68户,730间房屋构成严重威胁。必须对滑坡病害进行研究和防治。通过对涉县西达镇河口村西小型滑坡区域内地质构造、岩土体特性、斜坡特征、滑坡发育特征和成因条件等进行了深入分析。在定性分析的基础上,结合一定的试验数据和数学模型的定量分析指出斜坡仍处于不稳定的状态,降雨、地表水和地下水对坡体稳定性影响较大,尤其是降雨,是滑坡发生发展和致灾的重要因素。
According to the field survey, the small western landslide in Hekou Village, Xida Town, Shexian County poses a serious threat to 68 households and 730 houses in Hekou Village. Landslide disease must be studied and controlled. Through in-depth analysis of geological structure, rock and soil characteristics, slope characteristics, landslide development characteristics and genetic conditions in the west small-scale landslide in Hekou Village, Xida Town, Shexian County. On the basis of qualitative analysis and quantitative analysis of some experimental data and mathematical models, it is pointed out that the slope is still in an unstable state. Rainfall, surface water and groundwater greatly affect the stability of the slope, especially the rainfall, which is the development of the landslide And disaster-causing factors.
