长三角地区富水软弱地层超深地铁车站施工关键技术研究

地铁车站建设是地铁路线规划中一个重要的环节，关系到城市交通缓解和人们的出行，超深富水地铁站的逆作法施工正是国家战略性工程建设与规划背景下，复杂地质条件地铁建设中迫切需要解决的问题。对此，以杭州地铁4号线官河站工程为例，对富水软弱地层超深地铁车站施工的关键技术进行探讨和研究，得到了相应的结论。

Study on Key Construction Technology of Ultra-deep Subway Station in Water-rich Soft Ground of Yangtze River Delta Area

The construction of subway station is an important link in subway line planning which concerns on urban traffic relief and people’s trip. The reverse building method of ultra-deep water-rich subway station is just the problem which needs to be solved urgently in subway construction in complicated geological conditions under the background of national strategic engineering construction and planning. Hence, taking Guanhe Station of Line 4 of Hangzhou Subway as an example, the key construction technology of ultra-deep subway station in water-rich soft ground is discussed and studied, and corresponding conclusion is obtained.
