双排桩对边坡稳定影响分析的仿真研究

Simulation Study on Stability of Slope with Double Row Piles

双排护坡桩作为新型的支护结构,近年来在深基坑工程中得到了广泛的应用,但在边坡治理中应用较少.针对这种状况,以沪蓉国道某典型滑坡路段为例,研究了其边坡稳定性,提出了双排桩优化设计的方法并进行了实例仿真.研究表明:将双排桩设计在边坡中部位移最大处时,能有效改变边坡的应力边界条件,提高边坡稳定安全系数,从而验证了双排桩优化设计理论的正确性.最后对该边坡进行了综合设计.

As a new style retaining structure, double row piles in recent years have been widely used in deep rarely excavation and rarely applied in slope disposal. Aiming at this condition, the slope stability of typical landslide segment in Hu rong national road is studied, and the optimum design method of double row piles is put forward. Case simulation is further conducted and the results show that stress edge conditions can be effectively changed and stability safety factor of slope can be improved when the double row piles are established at the position with maximal displacement. Thus, the correctness of optimum design theory of slope is verified. Finally comprehensive design for the slope is processed.
