Abstract
Shanchiao fault is located in the west of Taipei basin, and the Quaternary sediments are above it. If the fault has an offset, the single overburden soil or growth strata will deform and cause shear zone. Definitely, the structures upon the overburden soil may cause some damages. So this study would like to know how the overburden soil deform and the inference of the area.
By using numerical simulation, ABAQUS(finite element method), we can simulate different depth of Shanchiao fault. If we design a vertical displacement 2.5 m, we can observe the propagation of shear zone at different thick of overburden soil. The result of analysis shows that the thicker overburden soil will reduce the development of shear zone.
By physical experiment, sandbox experiment, we can simulate the deformation of growth strata and the propagation of shear zone. The result of experiments show that the shear zone will propagate rapidly from the existed shear zone at footing wall.
