摘　　要：文章针对云峰水电站49号坝段左闸墩沿通气管分布竖向贯通性裂缝,设计采取对裂缝进行化学灌浆的加固方案,并在裂缝两侧布置并缝筋,闸墩表部配置面筋,增设预应力锚索。通过计算分析得出:该加固处理设计方案在技术上是可行的。The vertical connectively cracks have formatted along the aeration pipe in the left pier of the No.49 dam section of Yunfeng hydropower station. It is designed to treat with the cracks by chemical grouting programme, disposal reinforcing steel bars on both sides of the cracks and concrete on the surface, and meanwhile increase the numbers of prestressed anchor cables. The reinforcement programme is technically feasible after calculated results that have been analyzed.
