Abstract
In the river drainage treatment project,the light bridge abutment of the small bridge is equipped with support beams.Due to long-term erosion by water flow,the support beams are exposed above the riverbed surface,seriously affecting the drainage and discharge of the river.In order to solve the drainage problem of the river,the original support beams need to be removed.This article demonstrates the impact of removing the light bridge abutment support beams on the pile foundation.The article uses finite element software to establish finite element models of the pre-,post-,and reinforcement schemes before and after the removal of the support beam,and obtains the internal force and displacement results of the pile foundation.The results show that the removal of the lightweight bridge abutment support beam has a significant impact on the pile foundation.Moving the support beam downwards and constructing a new support beam at the top of the pile,the reinforcement scheme after removal is feasible,providing reference and assistance for the treatment of river surges under the bridge.关键词
