||Taiwan is located in between the boundaries of the Eurasian and Philippine |
plate, so the use of the land over the fault is a major issue. The dislocation
provokes a deformation in the surface causing an angular distortion; it could make
the upper side of the fault or the architectures surrounding it to get damaged,
causing structures to collapse. We can decide to use bigger projects, preventing
methods to reduce human and financial losses.
The majority of previous studies take finite element methods to simulate the
behavior of faults, and use the disadvantages of grid simulations like: particle-
degree rotation and limited displacement, the inseparability of particles, the
inability to detect particle contact situation, large changes can’t be simulated and
the show up and extension of cracks can’t be observed. Therefore, this research
uses discrete element method-PFC, simulating the dislocation of the fault after the
overburden of the top of the fault is affected by the displacement situation of the
bottom part’s dislocation. In the research of Liao(2013) ,the stiffness of the
particle’s contact, shear stiffness and particle basic friction are related to the
integral friction; the research of Sawwaf (2010) simulate Geo-grid in sand layers
loading plant by FE and compare it to the physical experiments. This research do
the original model by Liao′s codes and add the grid in the model to do the loaded
plant test, then compare to Sawwaf′s laboratory model.
The future research directions are for increasing the geo-grid in layer, and
simulate the lower friction of angle to discuss the result of Geo-grid, and use the
improved model to compare the bearing capacity.
