跃进水库滑坡机理分析及风险评估

Mechanism Analysis and Risk Assessment of Landslides in Yuejin Reseervoir

通过对跃进水库管理房前滑坡的成因进行深入分析,并对现存滑坡体的稳定状态与潜在滑坡风险的进一步综合评估,结果表明,该地区滑坡的形成内因主要包括坡体的不良岩土组合和结构特征,连续强降雨引发雨水的渗入、冲蚀是斜坡变形、滑坡的重要诱因。对该滑坡体稳定性计算结果显示,在天然状态和饱和状态下滑坡体仍处于不稳定状态,存在进一步发展的可能,并提出了相关治理建议,可供类似滑坡处理借鉴。

An in-depth analysis is carried out on the causes of the landslides occurred in front of the management building of Yuejin Reservoir.The stability status and potential landslide risks of the existing landslide body are further evaluated comprehensively.The results show that the internal causes of the landslide mainly include the combination of weak rock and soil and the structural characteristics of the slope.Rain water infiltration and erosion due to continuous intensive rainfall are important inducement for slope deformation and landslide.The stability analysis of the slope shows that the landslide body is still in unstable states in both natural and saturated conditions with further development possibility.Then,corresponding treatment measures are proposed.It can be useful reference for the treatment of similar landslides.
