摘要
为验证先施工换乘车站暗挖段方案的可行性,以青岛地铁5号线澳柯玛桥站暗挖段和邻近建(构)筑物为研究对象,通过有限元软件建立地层结构三维模型,对侧穿澳柯玛立交桥和新园公寓的换乘车站暗挖段进行了施工阶段模拟,分析了换乘车站暗挖段对邻近建(构)筑物的影响.结果表明:换乘车站暗挖段对澳柯玛立交桥的影响主要在于桥桩差异沉降;对新园公寓的影响较小,但应注意新园公寓的倾斜变形;车站拱部开挖是换乘车站暗挖段的关键施工环节,在实际施工过程中应加强对该施工环节的变形监测.数值模拟结果和现场监测数据表明,澳柯玛桥站邻近建(构)筑物风险可控,验证了先施工换乘车站暗挖段方案的可行性.
Abstract
In order to verify the feasibility of constructing the underground section of the transfer station firstly,the underground section of Aokema Bridge Station of Qingdao metro line 5 and the adjacent buildings was taken as the research object.A 3D model of the formation structure was established by finite element software to simulate the construction stage for the underground section of the transfer station passing through Aokema overpass and Xinyuan apartment.The influence of the underground section on the adjacent structures was analyzed.The results show that the main influence of the underground section of transfer station on Aokema overpass is the pile difference settle-ment;The influence on Xinyuan apartment is smaller,but the tilting deformation should be focused on;The exca-vation of station arch is the key link in the excavation section of transfer station,which should be strengthened in the actual construction process.Combined with the data of numerical simulation and field monitoring,it is shown that the risk of the adjacent structures of Aokema Bridge Station is controllable,the constructing the underground section of transfer station is feasible.
