摘　　要：本文以某城市综合管廊工程为例,根据该工程的设计依据、设计原则及设计情况,针对实施过程中的重难点进行实施方案比选。对创业大道管廊下穿XX高速区段,拟采用整体顶进法、暗挖法以及盖挖法,从安全适用、经济合理、确保质量及保证工期等进行多因素比对,最终选取经济、快速、安全的整体顶进法作为设计和施工方案;对永青路浅埋隧道群区段,结合其地质及环境情况、断面及埋深等因素,通过工程类比,选取新奥法原理进行设计,双侧壁导坑法进行施工。This paper takes an urban comprehensive pipe gallery project as an example, and compares the implementation plans according to the design basis, design principle and design situation of the project. For the XX expressway section under the pipeline corridor of Chuangye Road, it is proposed to adopt the integral jacking method, underground excavation method and cover excavation method, and carry out multi-factor comparison from safety application, economic rationality, quality assurance and construction period, and fnally choose the economic, rapid and safe integral jacking method as the design and construction scheme. Based on the geological and environmental conditions, the section and the buried depth of Yongqing Road shallow-buried tunnel group section, the new Austria method principle is selected by engineering analogy, and the double sidewall tunnel method is constructed.
