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 waterrich sand stratum. Taking a tunnel in Shenzhen as an example, the paper introduces the construction case of largespan, flattop, 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: waterrich sand stratum, mined tunnel with shallow cover, ground surface settlement
