提出了预测地震荷载作用下土坡永久位移的Newmark滑块法的新概念。以水平地面加速度作为输入运动，在路堤内部移动刚性圆形滑块。研究了地面最大水平加速度、速度和位移；地震反应谱对加速度、速度和位移的最大值；最大永久位移对应的反应谱的值；地震加速度的谱强度和主频对永久位移的影响。
A new concept of Newmark's sliding block method for predicting permanent displacements of earth slopes subjected to seismic loading is presented. Horizontal ground acceleration is used as input motion to move a rigid circular sliding block inside an embankment. The effect of the maximum ground horizontal acceleration, velocity and displacement; the maximum value of the response spectrum of the earthquakes for acceleration, velocity and displacement, the values of the response spectrum corresponding to the maximum permanent displacement; and spectrum intensity as well as predominant frequency of the earthquake acceleration on the permanent displacement are studied.
