Rotating Block Method for Seismic Displacement of Slopes of Saturated Clay

Zeng, X. / He, C.

A rotating block method is developed to calculate the rotational displacement of slopes of saturated clay under seismic loading. The method is similar to the pseudo-static sliding block method of Newmark and is quite easy to use in design calculations. When the threshold acceleration for rotation is exceeded, the slope will start to rotate until the angular velocity for rotation is reduced to zero. Rotational displacement will be accumulated each time the threshold acceleration is exceeded during ground vibration. The influence of ground motion characteristics on the computed slope deformation is evaluated. Implications for design are discussed.
