【摘要】 介绍了新的支护结构的支撑形式 ,即永久性支撑结构体系。该结构体系在土方工程施工阶段可作为支护结构的支撑而存在 ;土方工程结束后 ,与混凝土结合在一起形成永久性框架式复合结构 ,避免了横撑式支撑所带来的拆迁临时支撑的繁重施工工序 ,同“逆作法”施工相类似 ,土方开挖结束以后 ,上下部施工可同时进行 ,缩短了施工工期 ,具有较好的经济效益更多还原

【Abstract】 This paper introduces a new bracing system, i.e., Strut as permanent structure(SPS) to support the retaining wall during the excavation. In this sort of structure, the strut is used not only a temporary material to support the retaining wall during excavation, but also a permanent structural element of the building after the excavation. Thus, the construction period can be shortened, and possible accidents, which can occur during the dismantlement of the brace, could be avoided. In addition, the more wide work\|space can be achievable.更多还原
