摘　　要：在花凉亭水库引水隧洞的加固设计中,为使其加固方案既能减少工程量、节省工程投资、降低施工难度和施工风险,又能达到除险加固之目的,结合现场实际情况以及对检测资料的分析,对原加固方案进行了优化调整,提出了切合实际的加固设计方案。具体为进口结构部分拆除重建,出口处在原闸墩迎水面粘贴钢板,每侧闸墩背水面增加厚度2.2 m,以改善闸墩局部受拉区受力条件。经加固后,隧洞满足安全运行要求。In the reinforcement design for diversion tunnel of Hualiangting Reservoir,in order to reduce the construction quantities,save the project investment,reduce the construction difficulty and risk and realize the goal of danger removal and reinforcement,in the combination of in-site practical condition and the analysis of check data,the original reinforcement scheme was optimized and adjusted and more practical reinforcement design scheme was put forward.The concrete design scheme was to remove partial inlet structure,rebuild outlet structure,paste steel plate on upstream face of sluice gate pier,and increase the thickness of downstream face of sluice gate pier to improve stress condition in its local tension area.After reinforcement,the tunnel meets the requirement of safe operation.
