【摘要】 针对长沙地铁1号线一期工程建设和营运可能对白沙古井的潜在影响,通过对长沙市轨道交通1号线一期工程沿线区域地质构造、水文地质与工程地质及工程施工方法分析,研究白沙井形成的自然条件,含水层的分布范围,补、排、径流特征,地下水动态变化规律,地铁线路与地下径流的关系以及施工降水和地铁线路对地下水流场的影响,提出预防控制措施,为工程建设和白沙井的保护提供了一定参考。更多还原

【Abstract】 The construction and operation of the first phase project of No.1 line of Chasha Metro may have potential impact on Baisha ancient well.The natural forming conditions of Baisha well,the distribution scope of the aquifer,the characteristics of recharge,drainage and run-off,the rule of the dynamic variations of ground water,the correlation between the Metro alignment and the underground run-off and the influence of dewatering and Metro alignment on the flow field of ground water are studied on basis of analysis on the geological structures,hydrogeology,engineering geology and construction methods along the first phase project of No.1 line of Chasha Metro.Furthermore,prevention and control measures are proposed.The paper can provide reference for the construction of the project and for the protection of Baisha ancient well.更多还原
