| 摘 要： | 隔河岩水电站压力隧洞是国内首次采用钢筋混凝土预应力衬砌结构，通过５年来对该结构的观测和资料分析表明，预应力在改善隧洞的结构应力和防止裂缝的产生方面效果显著，同时表明隔河岩采用后张法施加预应力是成功的，为今后大直径、高水头隧洞的设计和施工提供了新的途径和经验

| Abstract: | Hennebique presterssed liner stuctures are used in pressure tunnels of Geheyan Power Station for the first time. Five years observation and data analysis indicate that there is a good result of improving the structural stresses of tunnels and avoiding producing cracks by use of prestress, and indicate that there in a good success in forcing prestress by post-tension. All of above will offer a new way and experience in the design of large-diameter and high waterhead in tunnel enginneering. |
