摘要
福建海西天然气二期管网工程黄石互通隧道主要位于缓丘地段,底板标高-15 m,埋深浅,通过分析评价其地层岩性、地质构造及水文地质特征,针对该浅埋隧道的特点,采用大气降水入渗法预测了隧道的涌水量,并用地下水动力学法进行验证计算,通过两种方法预测结果的相互验证,进而提出了隧道涌水量施工设计预测数据,且在工程实践中得到了验证,保证了隧道安全施工。
Huangshi tunnel of Fujian Haixi Second Phase Pipeline Network Project is located mainly in the gently rolling hills and is shallowly buried with its floor elevation of- 15 m. Through analyzing the characteristics of geological stratum,geological structure,hydrogeology,etc.,the atmospheric precipitation infiltration method is adopted to forecast the amount of waterin flow in the tunnel,and the ground water dynamics method is adopted to verify the calculation.Then the forecast data ofthe amount of water in flow in the tunnelare obtained by means of mutual verification of the two methods. The forecast data are verified in the project practice,which ensures the tunnelconstruction safety.
