摘要
本文对仙游抽水蓄能电站工程2号引水隧洞充排水试验过程中所观测记录到的实测资料进行分析,讨论高压隧洞围岩承载、衬砌与围岩之间渗流场而形成渗流力等理论概念,通过实测资料进一步说明隧洞衬砌混凝土允许开裂、由经高压固结灌浆的围岩来抵抗内水压力及承担防渗的设计符合实际,供同类工程参考与借鉴。
Actually measured datas recorded by observation in Water Filling and Discharging Test Process of Xianyou Pumped Energy Storage Power Station Project No. 2 Drainage Tunnel are analyzed. Load bearing on surrounding rock in high pressure tunnel, formation of seepage force in seepage field between lining and surrounding rock, and other theory concepts are discussed. It is further explained by actually measured data that cracks are allowed on tunnel lining concrete, design of resisting inner hydraulic pressure and bearing anti-seepage by surrounding rock undergoing high pressure consolidation grouting is in line with actual condition, which can provide reference for similar projects.
