Numerical Analysis of Bridge Caisson Foundation due to Riverbed Erosion

Abstract:

Keywords： Scour Depth, Water flow Force, Finite Element Method ABSTRACT. In recent years, the researches on the impact stability of piers based on river erosion are concerned in Taiwan. Therefore, it is an important issue to estimate accurately the scour depth, to calculate the water flow force on bridge pier, and to establish the close mechanism of bridge for saving lives. This research is a case study on Paulon Bridge by finite element method (FEM) Plaxis 3D Foundation for simulating analysis the caisson foundation in bridge pier scour. Firstly, we infer the flood level, the speed of flow in the different frequency year, the whole bridge safety coefficient, and the inclination angle of pile based on the simulating analysis to build the warning system. We compare the data by FEM and observing data in order to confirm the validity of FEM.
