抗滑桩在路堑边坡治理中的应用分析

以向家坡路堑边坡治理工程为例,结合该边坡实际情况,采用传递系数法,将此边坡分成5条滑块并对其下滑推力和安全系数进行了计算.计算结果表明:天然状态下此边坡不会产生滑坡,而在滑坡土体饱和的状态下,该边坡稳定性迅速降低,极易产生滑坡等地质灾害.根据传递系数法所获得的结果,对饱和状态下此边坡在有、无抗滑桩防护状态两种工况下的滑坡情况进行了数值模拟.抗滑桩能够有效地减小边坡的水平位移、阻止边坡下滑、提高边坡稳定性.

Application of Anti-Slide Pile in Governance of Cutting Slope

Taking Xiangjiapo cutting slope treatment project as example and combining with the actual situation of the slope, the author divides the slope into five slides and calculates the slide force and safety coefficient by using transfer coefficient method. Results show that this slope does not slide in natural condition but the stability of the slope quickly decreases and geological disaster such as landslide happens easily in saturated state. According to the results obtained from transfer coefficients method, the numerical simulation is done with using or not using anti-slide pile in saturated conditions. The numerical simulation results show that the anti-slide pile can reduce the horizontal displacement, prevent slide and enhance the stability of this slope.
