| 摘 要： | 在水文地质调查的基础上,查明慈母山隧道施工期涌水来源主要为松散堆积层孔隙水、基岩风化裂隙水和碎屑岩孔隙裂隙水,通过抽水、注水、压水试验,获得慈母山隧道各段围岩体的渗透系数,应用地下水迳流模数法、大气降水渗入量法及地下水动力学水平坑道疏干法对施工期的隧道涌水量进行预测,并确定了各地层的涌水方式,提出施工期以堵为主的工程防治措施。

| Abstract: | The hydrogeological investigations finding that the loose accumulation horizon pore water,weathering fissure water in bedrock and clastic rock fissure water is the major source of gushing.in order to obtain the permeability coefficient of rock mass,in-site tests such as Pumping test,water injection test and water pressure test have been performed.the construction period inflow has been estimated by runoff modulus method,air precipitation supplies method and dewatering method.The patterns of gushing in different strata also been ascertain.it is recommended that The water plugging measure based on shut-off during construction period. |
