后路隧道施工重点及难点分析研究

摘要

本文主要以中石化中原建设工程有限公司承建的海西天然气管网二期工程-后路隧道工程为例，分析研究大坡度、小断面隧道施工中的控制重点、难点及相关处理措施，并通过对隧道开挖的重点环节进行分析研究来确定相应的应对措施，旨在为今后类似情况的隧道施工提供科学依据。%Mainly taking hercynian gas pipeline project phase ii - posterior tunnel project which is erected by Sinopec Zhongyuan Construction Engineering Co., Ltd as an example, this article analyses the control points, difficulty and relevant treatment measures of large slope and small cross section tunnel construction. Moreover, by analyzing the key link of tunnel excavation, this thesis determines the corresponding countermeasures, aiming at providing a scientific basis for the similar tunnel construction in the future.
