| 摘 要： | 通过分析阳江抽水蓄能电站高压隧洞段的工程地质条件,从隧洞的覆盖层厚度、围岩水力劈裂、围岩渗透稳定性方面进行分析判别,结果高压隧洞段Ⅰ~Ⅱ类围岩满足采用钢筋混凝土衬砌的工程地质条件,但断层和裂隙密集带发育的Ⅲ~Ⅳ类围岩在高水头压力作用下会发生渗透破坏,需专门进行固结灌浆处理。

| Abstract: | Through the analysis on high pressure tunnel engineering geological condition of Yangjiang pumped storage power station, from the aspect of cover thickness of tunnel surrounding rock, hydraulic fracturing and rock seepage stability, the I-II surrounding rock of high pressure tunnel meet the engineering geological conditions of the reinforced concrete lining, but seepage appears at the surrounding rock of the fault and fissure zone III ~ IV under high water pressure, so it needs specialized consolidation grouting. |

| Keywords: | high pressure coverage ratio surrounding rock reinforced concrete lining |
