Abstract

Liquefaction phenomenon often occurs for loose materials is the phenomenon that the load capacity of the material is reduced with the sudden increase in pore water pressure due to the effect of dynamic loads and especially loads gravity caused by earthquakes with very fast time. This phenomenon is one of the most dangerous destructive phenomena for local dams when subjected to dynamic loads. This paper presents the dynamical theory bases as well as how to solve dynamic nonlinear problems for local material dams to determine the liquefaction conditions of local material dams on non-rock ground.
