摘要:
以三峡库区左岸归州老城滑坡为例,利用Janbu条分法和推力传递法,分析了天然抗剪强度指标c0、φ0值 和饱和csat、φsat值与滑坡推力和治理造价的关系。通过综合研究和比较,发现φ值对稳定系数、剩余下滑力的影 响要明显高于c值,φ值成为治理设计中保证治理安全和控制造价的关键因素。因此,在滑坡稳定性分析和治理 设计中,选取合理的φ值具有重要意义。
Abstract:
Taking the Guizhoulaocheng landslide on the left side of the Three Gorges Reservoir as an example, the relation between the intact c0,φ0and the driving forces, the relation between the intact c0,φ0and the treatment design, the saturated csat,φsatand the driving forces, the saturated csat,φsatand the treatment design are analyzed by the methods of Janbu Slices and driving force transfer. After the analysis and comparison of the computing results, it is suggested that influence of theφ value on the safety factor and the driving forces is much apparent than that of c value, andφ value is the most critical factor to ensure the safety and investment of the slide- controlling engineering. Therefore, it is significant to choose a reasonableφ value in the stability analysis and the controlling design of landslides.
