摘　　要：在现行的隧道设计施工规范中,还没有明确规定小净距隧道的设计、施工规程。文章结合工程实例介绍了小净距隧道的开挖顺序和围岩支护加固方式,以及中央岩柱加固、监控量测等关键工序,对小净距隧道施工质量的控制作了初步探讨。Up to now there are no explicit specifications in our country for the design and construction of twin tunnels with small spacing. Through an example of practical engineering this paper introduces the key processes and technology of the construction for twin tunnels with small spacing, such as: excavation sequence, support of surrounding rocks, rock pillar between twin tunnels and the reinforcement and monitoring of it. The paper also discusses how to control the quality of construction for twin tunnels with small spacing.

关 键 词：双洞小净距隧道 开挖顺序 施工监控
