摘要:
穿越富水砂层一直是浅埋暗挖隧道的难点。以深圳某交通隧道为依托介绍在地质以流砂层和淤泥质砂层为主、隧道结构为大跨度、平顶、浅埋和小曲线半径的情况下,采用一系列措施使隧道顺利贯通、并有效地控制地表沉降的施工实例。
关键词: 富水砂层, 浅埋暗挖隧道, 地表沉降
Abstract:
It is difficult for mined tunnel with shallow cover to cross waterrich sand stratum. Taking a tunnel in Shenzhen as an example, the paper introduces the construction case of largespan, flattop, shallow buried and small curve radius tunnel successfully crossing stratum mainly consisting of quicksand and muddy sand. A series of measures taken during the tunnel excavation ensured the successful tunnel breakthrough and effective control of the ground surface settlement.
Key words: waterrich sand stratum, mined tunnel with shallow cover, ground surface settlement
