摘要

大连填海区因其特有的工程地质条件,成为大连地区地下工程建设的难题。大连地铁二号线海之韵站位于大连市东港填海区,在设计和施工过程中遇到了各种问题,通过精心设计、现场试验,确保了工程的成功实施。对工程场地饱和软土震陷特性试验成果及处理措施进行了详细介绍,可为类似工程条件下的地下工程设计提供参考。
        The reclamation area of Dalian becomes a difficult problem of underground engineering construction in Dalian due to its special engineering geological condition. Metro line 2 Haizhiyun station in Dalian is located in Donggang reclamation area of Dalian. During the period of design and construction,it encounters all kinds of problems. The successful engineering implementation is guaranteed through the meticulous design and field test.The test result and treatment measures of seismic subsidence characteristic of saturated soft soil of engineering site are introduced in detail,so as to provide reference for the underground engineering design under the similar engineering condition.
