Abstract
The seismic dynamic response analysis of slope engineering is an important part of the framework of slope seismic performance design and evaluation, as proposed in Chap. 3, which is developed upon determining the seismic ground motion excitation of the slope engineering site. Slope seismic response analysis methods can generally be divided into the quasi-static method, response spectrum method, nonlinear dynamic time-history analysis method, and large deformation analysis method. Under seismic dynamic action, the large deformation analysis method can well represent the dynamic disaster process caused by impact failure after slope instability. These methods can also be integrated to describe the entire evolution process of the slope seismic performance state. The full process analysis of slopes under seismic dynamic action can be realized by integrating the large deformation analysis under seismic dynamic action from plastic finite deformation to crack occurrence and development, and ultimately to the final unstable flow.
