摘要:本文以武汉地铁二号线及四号线洪中区间隧道为背景，针对多条重叠隧道小间距的特点，提出盾构隧道“先下后上”的总体施工原则，重点阐述了盾构掘进控制、夹层土注浆加固和洞内临时支撑隧道加固等关键措施，通过监测结果有效验证了其成功，可为今后的重叠隧道设计、施工管理提供经验借鉴。
Abstract: Based on overlapping tunnel section from Hongshan Square Station to Zhongnan Road Station of Line No.2 and Line No.4 of Wuhan Metro, this paper proposed a principle of "finish the following part first" for subway construction considering the features of overlapping tunnels with short-distance. It mainly elaborated several key measures, such as shield tunneling control, grouting for mezzanine soil, temporary support in tunnels. Then the monitoring results proved the feasibility of the measures, so that this paper can provide reliable experience for the designation of overlapping tunnels and construction management in the following years.
