南充村山体受强降雨影响发生滑坡已造成重大的人员和财产损失,通过工程勘察对区域内地质构造、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运用边坡稳定分析软件分析评价了斜坡的稳定性,指出斜坡仍处于不稳定状态,降雨、地表水和地下水对坡体稳定性影响较大,尤其是动水压力,是滑坡发生发展和致灾的重要因素。结合区内地质灾害发育特点和坡体结构特征,提出了采用抗滑桩、预应力锚杆格构、挡墙和排水相结合的综合防治方案。
The landslide caused by strong rainfall in the mountain of Nanchong Village has caused significant personnel and property losses. Through geological survey, the geological structure, the characteristics of rock and soil, the characteristics of the slope, the development characteristics of the landslide and the causes and conditions of the landslide have been deeply analyzed. On the basis of qualitative analysis, the slope stability analysis software is used to analyze and evaluate the stability of the slope, pointing out that the slope is still in an unstable state. Rainfall, surface water and groundwater greatly affect the stability of the slope, especially hydrodynamic pressure. An important factor in the development and disaster of landslides. Combined with the characteristics of geological disasters in the area and the structural features of slope, a comprehensive control scheme using anti-slide piles, prestressed anchoring grids, retaining walls and drainage is proposed.
