摘要
根据工程地质和水文地质条件,在综合考虑结构埋深和工程造价的基础上,对郑州城郊铁路采用的矿山法结构下穿高速施工方案作了介绍,指出在施工过程中采用台阶法、超前大管棚等措施,保证了结构的安全。
According to the engineering geology and hydraulic conditions,considering the structure depth and engineering cost,the paper intro-duces the construction scheme of Zhengzhou urban railway undercrossing the expressway with mining method,and points out benching tunneling method and advanced shed and other construction measures,which guarantees the structural safety.
