【摘要】 在毕肖普法中考虑地震过程产生的竖向力和水平作用力,建立边坡的地震破坏模型。对于设计台阶和不设计台阶边坡进行抗震分析,探讨台阶宽度对边坡抗震的影响。通过编写vb工程计算软件,进行迭代计算得出,在地震荷载作用下,边坡从失稳状态达到临界状态时,都将对应一个临界台阶宽度的结论及其变化规律。这为边坡抗震设计提供重要的参考依据。更多还原

【Abstract】 The vertical force and horizontal force that occur in earthquake are considered according to the Bishop method.A destruction model of slope is established,and whether the absence of the steps will influence the seismic performance of the slope is analyzed,and the step width influence the seismic performance of the slope is also analyzed.The numerical results given by a calculation program developed by the authors indicates that it will correspond to a critical width of step when the slope comes from the unstable state to the critical state under the load of earthquake,which provides significant reference for the design of slope.更多还原
