摘　　要：作者参加了宜昌市火车站下云集公路隧道软岩浅埋段的配合施工 ,根据现场施工及设计情况 ,本文回顾分析了该段隧道开挖方法的选择、支护结构设计及有关施工工艺、施工量测标准的制订及实施情况 ,以及施工支护情况等 。The author participated the cooperating construction of shallow tunnel section with soft surrounding rock in the Yun Ji Highway under the Yichang Railway Station. According to the in situ construction and design situations, the selection of excavating method for such tunnel section, the design of supporting structure and its relative construction techniques, working out the construction measuring standards and their implementation situations, as well as the situations for constructing the supports,etc,are reviewed,analyzed and described in this paper.The paper provides a scientific practice for design and construction of tunnel with the similar working sections hereafter.
