摘要
盾构施工技术在城市地下铁路隧道工程建设中应用广泛。在盾构隧道施工中,盾构穿越构筑物桩基技术难度高,风险大,费用分析困难。本文结合在建城际铁路工程,建立了对盾构切削穿越机场地下通道底部管桩的工程模型,通过合理的施工组织设计,对其工程造价进行了分析,可为今后的类似工程施组组织设计与工程费用分析提供经验参考与借鉴。
Shield machine is widely used in railway tunnel construction.It’s difficult to calculate the cost of which crossing the pile foundation due to the big construction difficulty and risks.This paper analyzes the cost of shield machine cutting through the bottom pipe pile of airport underpass based on the reasonable construction arrangement design of aintercity railway project under construction.It can provide experience and reference for the construction arrangement and cost analysis of similar shield railway tunnel construction projects in the future.
