Research Status of 1-D Nonlinear Soil Layers Seismic Response in Time Domain

Abstract

The soil dynamic constitutive model has always been one of the frontier topics in soil dynamics. In the past few decades, the constitutive model of soil has been rapidly developed, and with computer technology and one-dimensional soil earthquakes. In the development of reaction analysis methods, many earthquake response models and calculation procedures for one-dimensional time domain nonlinear soil layers have emerged. In this paper, the deterministic method of theoretical analysis is used to summarize the development of soil constitutive model in soil-time seismic nonlinear method. The time-domain nonlinear soil used in different periods is introduced according to the development order of constitutive model. Layer seismic response procedures and their advantages and disadvantages, as well as the latest improvements made to them. Finally, the development direction of nonlinear method programs is prospected.
