Abstract

Lateral spreading is one of the most significant destructive and catastrophic phenomena associated with Liquefaction caused by earthquake and it can cause very serious damage to structures and engineering facilities. The aim of this study is to evaluate Liquefaction-induced Lateral spreading and nd new relations using Gene expression programming (GEP), which is a new and developed generation of genetic algorithms approaches. Since there are complicated, nonlinear, and higher-order relationships among many factors affecting the Lateral spreading, GEP was assumed to be capable of finding complex and accurate relationships among the involved factors. This study includes three main stages: (i) compiling available database (484 data); (ii) dividing data into training and testing categories; and (iii) building new models and proposing new relationships to predict ground displacement in Free face, Gentle slope, and general ground conditions. The results of modeling each of these different ground conditions were presented in the form of mathematical equations. At the end, the final GEP models for 3 different cases of ground conditions were compared with Multiple Linear Regression (MLR) and other published models. The statistical parameters indicated the higher accuracy of GEP models over other relations.
