Abstract

Failure of structures may force us to build a new structure. This may raise economic and environmental issues. Thus, building safe structures is essential for sustainable development. Liquification is one of the most critical geotechnical disasters that occurs in saturated sandy soils during earthquake or dynamic loading. To know the behavior of the liquefaction of soil, past studies were conducted analytically or experimentally. But this research is observing the soil liquefaction behavior numerically by conducting numerical modeling of vertical settlement, effective stress, and excess pore pressure, during earthquakes considering various soil and structural conditions utilizing Plaxis 2D FEM software. The calibration of the model was performed with a shear box test in the laboratory. Static shear stress phenomenon in liquefaction creates suction at mid of model and increases the effective stress at these specified locations. The load increases the generation of excess pore pressure.
