Abstract
本申请涉及一种地铁区间中间风井结构体系及施工方法，地铁区间中间风井结构体系采用非对称平面布局，使第一区间隧道贯穿明挖中间风井结构内部，第二区间隧道位于风井轮廓外侧并通过连通道与风井联通，打破传统对称布局对区间隧道线间距的依赖及“风井需同时覆盖双线隧道或对称分布于隧道两侧”的设计前提，中间风井主体结构平面布置较灵活，可减少中间风井建筑规模，减少与周边管线、建构筑物、道路等的冲突，减少乃至规避了地上建构筑物、地下管线等条件限制下因传统对称布局导致的既有设施大量改移难题，降低了区间隧道线路平面布置的难度，降低工程实施代价，实现复杂环境下中间风井结构与区间隧道的高效衔接，提升平面布局灵活性。
