Hydrodynamic Simulation of WeiYi Bridge in LiuZhou City, Guangxi Province, China
Abstract. Liuzhou is an important city of flood protection in china.Flood protection assessment for any new relational-water project is prerequisite.In order to understand the impact to river flow,a 2-D hydrodynamic model is set up,and use ADI method to solute partial differential groups.The results can be shown as fellows: Computation is fast steady and convergent by ADI method,and associated errors of model control is satisfied.The bridge pier has major impacts on river flow.Velocity change due to bridge built could lead to riverbed erosion between piers,and siltation along the upstream and downstream of the Weiyi bridge.Water level could be rised in the bridge upstream with the raised water level of about 0.08m,which might affect drained floods to a some degree.
