摘　　要：结合杭州市某市政连通工程,为确定其最为合理的实施方案,根据该市政连通隧道的特点,分析隧道实施对周边建筑物和下方既有地铁隧道的影响,对比明挖法、矩形顶管法、盾构法等隧道施工工法在项目中应用的优缺点。基于一定的理论计算分析,表明该连通工程采用明挖工法和叠落布置方案最为合理,可为类似的隧道工程方案研究提供借鉴。Combined with a municipal connection project in Hangzhou,in order to determine the most reasonable implementation scheme and according to the characteristics of the municipal connection tunnel,the impact of the tunnel implementation on the surrounding buildings and the existing subway tunnel below is analyzed,and the advantages and disadvantages of tunnel construction methods such as open excavation method,rectangular pipe-jacking method and shield method for the project are compared.Based on certain theoretical calculation and analysis,it is shown that the open-cut excavation method and overlapping layout scheme are the most reasonable for the connecting project,which can provide reference for the study of similar tunnel engineering schemes.
