摘　　要：针对本工程溢洪道闸墩预应力锚杆发生断裂,导致弧门支座承载能力不足的请况,进行断裂原因分析。根据结构布置特点和工程施工状况,通过分析和计算,提出了取消原钢梁支座、增加钢筋混凝土牛腿作为弧门支座、在闸墩表面局部受拉扇形区设置钢板条替代受拉钢筋的加固处理方案。该加固处理方案解决了弧门支座承载能力不足的问题,研究成果对类似工程问题的处理有一定参考价值。The bearing capacity of the radial gate bracket is insufficient due to the breakage of the pre-stressed anchor rods in the spillway gate pier of Tendaho project .To solve this problem ,a reinforcement measure was proposed here after detailed analysis and computation based on the characteristics of structure arrangement and construction condition .According to this measure the steel beam bracket was replaced by reinforced concrete corbel bracket ,meanwhile the steel bars in the fan-shaped area on the surface of the gate pier were replaced by the reinforcing steel plates .This measure will solve the problem of lacking bearing capacity at the gate bracket ,which has certain referential value to similar projects .
