摘　　要：城市中的各种地下管线,尤其是燃气管线,极大地影响着地铁隧道的施工安全和施工工期。以深圳地铁4号线二期工程上民区间浅埋暗挖隧道施工为例,介绍暗挖施工所采取的管线保护措施,重点阐述超前大管棚、袖阀管注浆和降土法3种技术方法的应用细节。通过这些技术方法的应用,有效地控制了管线的沉降,保证了管线的安全和施工的顺利进行。The various utility lines in urban areas, especially the gap pipelines, have great influence on the construction safety and construction schedule of the Metro tunnels. The measures taken to protect the utility lines during the shallowcovered mining construction of Shangmeilin-Minle section of phase II project of line 4 of Shenzhen Metro are presented, with the focus being placed on the advance large pipe roof, soletanche grouting and soil releasing. In the end, the settlement of the utility lines is effectively controlled, the safety of the utility lines is ensured and the successful construction of the project is guaranteed.
