深圳沙荷路滑坡特征与稳定性分析

Analysis on Landslide Characteristics and Stability of Shenzhen Shahe Road

深圳沙荷路滑坡位于深圳市东北部泥质粉砂岩地区,坡体软弱夹层多,结构面大角度相交,稳定性差,加之边坡过陡,雨水渗入使裂缝持续深入及扩张,坡内形成多个蠕滑变形带;鉴于边坡处于变形初始阶段,及时采用预应力锚索+格构梁+截排水系统综合治理,成功阻止了边坡继续滑移。

Shahe Road landslide locates in muddy siltstone area of northeast Shenzhen.The landslide body is weak with multiple interlayer and structural faces are crossed with large area,so it is unstable.Besides,the slope is too steep and rainwater is easy to permeate causing crack propagation,and thus many creeping deformation zones are formed.For the slope is in the initial stage of deformation,comprehensive measures of prestressed anchor cable,lattice beam and drainage system have been taken in time to successfully prevent continuous slippage.
