临时支护与永久支护相结合设计在某工程中的应用
摘要:结合具体工程实例,设计了双排桩、土钉墙、桩锚支护、桩顶小挡墙多种支护结构的组合体系,解决了有限空间内临时与永久两种工况下的边坡支护问题。监测结果表明,支护结构位移控制较好,碎石土地层中预应力锚索短期内预应力损失较小。
Abstract:A composite design of multiple supporting structures is applied in a specific project,including double row piles, soil nailing wall, pile anchor support and small retaining wall on the top of piles. This system could solve the problem of slope support under two working conditions of temporary and permanent in limited space. The monitoring results show that the displacement control of the support structure is well, and the prestress loss of the prestressed anchor cable in the gravel soil layer is small in the short term.
