摘要
结合广州地铁五号线小北站西端站厅通道工程实际,主要介绍TSS管的制作及在本工程浅埋暗挖隧道过含水砂层中的应用,实践证明,TSS工艺能有效加固掌子面,控制地表沉降,为暗挖隧道通过含水砂层提供技术储备,值得进一步推广。
Combining with west station channel engineering practice at small north station in No.5 line of Guangzhou,this paper mainly describes the manufacture of TSS tube and its application in shallow and bored tunnel engineering crossing water sand layer.Practice shows that： TSS technology can effectively strengthen tunnel face,control surface subsidence,and provide technical reserves for bored tunnel across water sand layer.Thus,it is worth further promoting.
