摘要

以拟静力法的理论框架分析了土工合成材料加筋边坡直线破坏模式下的地震稳定性,整个计算过程采用极限分析的动力学理论,推导出的表达式能够容易地计算出地震荷载作用下为阻止边坡破坏所必需的加筋力和屈服加速度系数的闭合解。
In this paper,the stability of slopes reinforced with geosynthetics is analysed within the framework of the pseudo-static approach under the seismic loading only for the translational failure mode.Calculations are conducted by applying the kinematic theorem of limit analysis,and each analytical expressions are derived that enable one to conveniently calculate the closed-form solutions of the reinforcement force required to prevent failure and the yield acceleration of slopes subjected to earthquake loading.
