槐树村滑坡稳定性分析及治理

Stability Analysis and Mitigation of a Landslide at Huaishu Village

采用极限平衡法及传递系数隐式解法可较为准确地反演出滑坡的滑带土参数和滑床形态。考虑到滑坡与铁路的特殊位置关系,采取了对滑坡裂缝的封堵及反压回填的临时措施,充分利用谷口两侧山体的稳定性,在谷口处设计多根锚固桩与多型排水沟相结合的永久防护措施,安全、有效地治理了该滑坡灾害。

The location of the slip surface and its shear strength parameters can be determined by using limit equilibrium method and transfer function with implicit solution with a relatively high accuracy.Considering the slip locations relatively close to the railroad alignment,the mitigation measures used both temporary solutions such as sealing off cracks and back surcharge at the toe of slip and long-term solutions such as permanent anti-slip caissons and drainage ditches at the mouth of the stable valley.It is approved that the mitigation measures are safe and effective.
