摘要
通常地下明挖车站主体轨排井段设计,主要通过设置锚索及围护结构共同抵抗侧向荷载。但是由于锚索其自身工艺条件等因素的限制,对地下空间开发影响较大,目前大多数城市已不推荐使用。本文针对某地下车站轨排井结构设计难点进行分析,结合车站自身特点采用箱型结构支护形式,在提高施工效率的同时避免了锚索的使用,为此类工程提供新的设计思路。
In general,the design of the main track panel shaft of underground open-cut station is mainly to resist the lateral load by setting anchor cable and retaining structure.However,because of the technical conditions of anchor cable,it has a great influence on the development of underground space,which is not recommended in most cities.Through the analysis of the difficult points in the structural design of the track panel shaft of an underground station,this paper adopted a boxframed structure supporting form in combination with the characteristics of the station,which could avoid the use of the anchor cable,and provide a new design idea for this kind of project.
