Abstract:Most of the existing 10 shipping hubs in Lianjiang,such as Jietan,have exceeded their service life,and there are hidden safety hazards in terms of plane layout,main structure,foundation treatment,and construction quality of buildings.Therefore,this paper proposes disposal plans for hidden safety hazards,including hub scrapping and demolition,reconstruction after risk removal,and unified cascade layout adjustment.Through technical and economic comparison,the paper recommends the unified cascade layout adjustment plan.This plan aims to build a comprehensive hub with navigation as the main function,which also considers power generation,irrigation,water supply,flood control,urban landscape,and other functions,so as to comprehensively utilize water resources and maximize benefits,which can provide a reference for the disposal of hidden safety hazards of hubs in similar rivers in the future.
