摘　　要：沿海挡潮闸长期受海水侵蚀、环境影响等作用,其钢筋混凝土结构已严重受到影响,目前普遍存在底板裂缝、脱空等隐患,须进行保护性加固处理。以新金清闸保护性加固为例,通过研究分析闸室开裂、闸底板裂缝及闸底板脱空等隐患产生的原因,提出利用减载、脱空区灌浆加固、柔性补缝及树根桩加固等措施,以达到保护性除险加固的目的。Due to long-time seawater corrosion and environmental factors,reinforced concrete coastal gates have serious structural safety performance with bottom floor crack and void,in need of protective reinforcement.Focusing on protective reinforcement of the Jinqing new sluice,by analyzing and studying the reason of gate chamber crack,bottom floor crack and void,the measures of load shedding,grouting reinforcement void,flexible patching and tree root pile were proposed in this paper to achieve protective reinfoercement goal.
