复杂环境条件下城市地下通道超浅埋暗挖施工技术

SUPER-SHALLOW UNDERGROUND EXCAVATION TECHNIQUE OF URBAN UNDERGROUND PASSAGE UNDER COMPLEX ENVIRONMENTAL CONDITIONS

武汉城区地下通道施工所处软弱且富水的地层,其顶部地下管网及周围建筑密布,为保证施工过程中地面城市主干道交通不受影响,采用超浅埋暗挖等施工技术,确保了工程施工的安全以及施工质量和工期的要求。

An urban underground passage construction project in Wuhan is located on a soft stratum with high water content, where there are dense underground pipeline networks and buildings on the top. To ensure that the urban artery traffic will not be influenced during the construction, a series of construction techniques, such as super-shallow underground excavation, etc., are adopted to successfully satisfy the requirements of construction safety, quality and schedule.
