Abstract
In order to investigate the failure effect of seismic fault and the slope stability under seismic damages along highways, the spatial distributions of earthquakes previously occurred in engineering research areas was qualitatively analyzed. Afterwards, the study put forward a seismic fault model along highways to analyze its kinematic characteristics. On this basis, by using ABAQUS finite element program, the seismic response of the selected representative cutting slope of highways in seismic damage areas was calculated. The displacement field output from the programs was used to analyze the displacement change in the top of the slope while the acceleration obtained from program was applied for calculating the coefficient of acceleration distribution. By substituting the stress field output by the dynamic finite element analysis software into the genetic algorithm (GA) program compiled by using MATLAB, the time interval curve of safety factors of the slope was calculated and critical slip surfaces can be intelligently searched. By doing so, the change law of safety factors with the change in acceleration of seismic waves and the value range of safety factors of the envelop diagram of slip surface can be obtained.
