| 摘 要： | 在高压输水隧洞及地下厂房围岩中，遇水膨胀的蚀变岩带十分发育。但根据水压致裂原地应力的测量结果及最小主应力设计准则，广州抽水蓄能电站的高压输水隧洞甚至高压岔管段均取消了钢衬。电站建成以来的安全运行表明，该设计是完全合理的。实践表明：在充分利用岩体自身的承载能力，优化工程设计方面，水压致裂原地应力测量具有十分重要的意义。

| Abstract: | In the surrounding rocks of conveying water tunnel with inside higher water pressure at Guangzhou pump storage project, the erosion belts expanding intensely with water being are quite developed. But according to the results of hydraulic fracturing test and the minimum principal stress criterion,the steel liners of the high pressure conveying water tunnel and even at the branch section are all cancelled,and just supported by reinforced concrete liner with thickness of 60 cm. The power station has being operated smoothly for years,which shows that the designing of the project is quite reasonable. |
