连江航运枢纽安全隐患处置方案

Disposal plans for hidden safety hazards of Lianjiang shipping hub

连江现存界滩等10座航运枢纽大都已超过使用年限,建筑物在平面布置、主体结构、地基处理以及施工质量等方面均存在安全隐患。针对此问题,提出枢纽报废拆除、除险重建和梯级统一调整布局等安全隐患处置方案。通过技术经济比选,推荐采用梯级统一调整布局方案,该方案将建设以航运为主,兼顾发电、灌溉、供水、防洪、城市景观等功能的综合枢纽,实现水资源综合利用和效益最大化,可为今后类似河流上的枢纽安全隐患处置提供参考。

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.
