For the slope stability evaluation of a sloping revetment located in a high seismic zone in Philippines,we analyze the study of these international seismic design codes,propose an appropriate seismic slope stability analysis method,stability criteria,and analysis process based on the specific design conditions of the project,and use the Newmark method and non-linear dynamic analysis to calculate the lateral deformations of the sloping revetment after earthquakes.The results indicate that the stability analysis of sloping revetment in high seismic zones should aim to control the lateral deformations,which under Level 1 and Level 2 earthquakes are advised not to exceed 5 cm and 30 cm respectively.When using the Newmark method for calculation,its upper bound displacement should be taken,and the distribution of residual displacement and maximum shear strain obtained from the nonlinear dynamic analysis can provide a more comprehensive design and evaluation of the seismic slope stability.
