针对边坡在地震力作用下的稳定性问题，在毕肖普法中考虑受地震力影响产生切向力和竖向力，建立线性边坡受力模型。对不同地震力偏角范围内边坡安全系数计算公式进行推导。编写 VB 工程计算软件进行迭代计算，得出在不同地震力偏角时边坡的安全系数和最小安全系数所对应的地震力偏角以及安全系数随不同地震加速度与震动时刻的变化规律，为边坡抗震设计提供重要的参考依据。

For the problem of the slope stability under earthquake force ,considering the vertical force and horizontal force under the earthquake force in the Bishop method ,the stress model for linear slope is built .Then the calculation for-mula for the safety factor of the slopes with varies ranges of different seismic force angle is deduced ,and the VB engineer-ing software is prorammed to get the slope’s safety factor and minimum safety factor in different seismic force angle through iterative calculations as well as the variation law of the safety factors along with different seismic acceleration and moment ,which could provide the important reference bases for the seismic design of slope .
