LIU Hao-yang
Abstract：Based on the Pearl River Delta water resources allocation project,the abnormal section of the first water filling test of the water conveyance tunnel from Gaoxinsha Reservoir to Shaxi High-level Pool was analyzed,and the corresponding measures were put forward.The analysis results of monitoring project data showed that the monitoring results of joints,seepage pressure and anchor cable anchorage force were obviously affected by the internal water pressure,which showed an unfavorable trend with the increase of the internal water pressure,and then showed a recovery trend with the decrease of the internal water pressure.According to the comprehensive judgment,there was seepage of internal water in the tunnel during the first filling and draining test.The possible hazards caused by leakage of the tunnel were analyzed,and the corresponding measures were proposed to ensure the safety and stability of tunnel operation.
