摘　　要：以广东省汕尾市陆丰湖东大桥桥闸建设工程为例,针对桥闸及建筑物严重老化,桥闸功能已无法达到新防洪标准要求,对现有桥闸进行拆除重建,并进行稳定性分析。确定采用开敞式平底宽顶堰,底槛高程设计为-2.70m,水闸净宽布置选定为5孔×12m,闸顶高程为3.90m。通过公式计算,确定闸室段抗滑稳定安全系数及最大最小基底应力之比、基底抗渗稳定与堤身抗滑稳定均满足规范要求,达到防潮减灾、行洪、挡潮的目标,为类似桥闸重建工程提供参考方案。In this paper, based on the bridge gate construction project of Lufeng Hudong Bridge, aiming at the situation that the bridge gate and its buildings are seriously aging and its function cannot meet the new flood control standard, the existing bridge gate is dismantled and rebuilt, and its stability is analyzed. The open flat bottom wide top weir is determined, the height of the bottom sill is designed as-2.70 m, the clear width of the sluice is selected as 5holes×12m,and the height of the sluice top is 3.90 m. According to the formula calculation, the safety factor of anti-sliding stability of the lock chamber section, the ratio of maximum and minimum base stress, the anti-seepage stability of the base and the anti-sliding stability of the dike meet the requirements of the code, and achieve the goals of moisture-proof and disaster reduction, flood discharge and tide retaining, which provides a reference scheme for similar bridge gate reconstruction projects.
