| 摘 要： | 在地铁车站设计中合理地采用明暗结合方案,能够充分发挥明挖方案的施工速度快、施工质量容易保证以及暗挖对地面交通和地下管线的干扰小,在埋深较大的岩石地区造价低的优点。以青岛地铁车站设计为例,探讨岩石地区明暗结合的车站设计特点,结合周围环境保护要求确定了明挖基坑的钢管桩+锚杆和喷锚不对称的支护形式,暗挖段以围岩条件为依据,分别采用了全长粘结型砂浆锚杆和中空注浆锚杆的支护形式,并通过数值模拟证实该方案均能满足工程设计要求,为岩石地区类似工程的设计和施工提供了参考。

| Abstract: | Cut-and-cover excavation is used properly in the design of subway station,which can display some advantages.The open-cut method is of fast construction and guaranteed construction quality,and the subsurface excavation has little influence on the ground traffic and underground pipeline and has low cost when constructed in deep rock region.The characteristics of subway station design excavated by cut-and-cover excavation combined method in rock region is studied based on the design of subway station in Qingda... |
