摘　　要：以珠江三角洲水资源配置工程为背景,对高新沙水库至沙溪高位水池段输水隧洞首次充水试验异常断面进行分析,并提出应对措施。监测项目数据分析结果显示,接缝、渗压及锚索锚固力等监测数据受内水压力影响明显,先随内水压力增大呈不利趋势变化,后随内水压力减小呈恢复趋势变化。经综合判断该隧洞在首次充排水试验期间有内水外渗情况发生,分析了隧洞渗漏可能造成的危害,并针对性提出缺陷处理措施,确保了隧洞运行的安全性和稳定性。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.
