砂卵石地层过既有线的地铁暗挖施工技术

Sandy pebble formation of existing subway underground construction technology

以成都地铁某车站穿越既有线设计施工为例,介绍了该施工方案的处理思路与施工步骤,并总结了地铁换乘节点施工技术及经验,经监测表明该施工方案安全可行,对类似工程具有一定的参考价值。

Taking the design construction of Chengdu subway station crossing existing line, the thesis introduces the construction scheme process- ing concept and construction procedures, summarizes construction technology and experience of subway interchange joint station. The monitoring results prove the safety and feasibility of the construction scheme, which has certain guiding value for similar engineering.
