本文采用拟静力法分析了一排桩加固边坡的地震稳定性。采用极限分析运动学原理与强度折减概念相结合的方法进行计算。考虑了对数螺旋滑动面,导出了计算地震荷载作用下边坡屈服加速度系数的解析表达式,以及将边坡安全系数提高到设计值所需的桩所提供的侧向稳定力。给出了典型算例的数值结果,验证了程序的合理性。此外,还讨论了水平地震系数对水平稳定力的影响以及在地震区的最佳桩位。
In this paper, the seismic stability of a slope reinforced with a row of piles is analyzed within the framework of the pseudo-static approach. Calculations are conducted by using a technique integrated the kinematic theorem of limit analysis with strength reduction concept. The log-spiral failure surface is considered, analytical expressions are derived that enable one to readily calculate the yield acceleration coefficient for the slope subjected to seismic loading, and the lateral stabilizing force provided by piles which is required to increase the slope safety factor to a design value. Numerical results for typical example are presented and the reasonableness of the procedure is verified. Furthermore, discussions are made in order to illustrate the influence of horizontal seismic coefficients on the lateral stabilizing forces and the optimal position of the pile in seismic area.
