【摘要】 为了查明武汉过江隧道所经长江区段内地下水流速、流向等水文地质参数,采用单井同位素稀释法代替抽水试验法测试水文地质参数,测试结果表明:江南孔含水层地下水流速下部略大于上部,流向为NE10°;江北孔含水层地下水流速上部大于下部,两者相差较大,与该井洗井情况有关,流向为NE50°.图1,表4,参10.更多还原

【Abstract】 In order to find out the hydrogeological parameters(groundwater velocity and direction)of underwater tunnel in Wuhan,the authors adopt the single well dilution method to replace pumping test and test the hydrogeological parameters,The result of test shows that:groundwater velocity of aquifer in Jiang-nan of deeper segment is more than that of upper segment,the direction of groundwater is NE10°;groundwater velocity of aquifer in Jiang-bei hole exists large discrepancy,has something with condition of washing hole,the velocity of upper segment is more than that of deeper segment,the direction is NE50°.1fig.,4tabs.,10refs.更多还原
