摘要
以基坑工程实例形式介绍了复合式土钉墙支护技术的应用效果,并论述了复合式土钉墙的计算方法和构造设计,提出选用复合式土钉墙支护方案的建议。复合式土钉墙是在传统土钉墙的基础上,配合采用预应力锚杆、水泥土搅拌桩、超前树根桩(微型桩)、S.M.W工法等技术措施,以控制土钉支护的变形,满足环境对支护的设计要求而形成的一种组合式支护技术。该支护技术能有效地缩短施工工期,具有成本低,适用面广,安全可靠等优点。
This paper introduces application effect of composite soil nailing walls, in the form of application instance on excavation shoring engineering. Simultaneity it also discusses calculation methods and basis structure. The advice to choose excavation shoring project is offered. Composite soil nailing walls is a supporting technique which combines with prestress anchor, mixing cement - soil pile, root pile in advance supporting(i, e. micropile), S. M. W method and so on, in order to control distortion of soil nailing walls, and to satisfy design demand of environment for excavation shoring. It can effectively shorten construction time limit for a project, and has advantages of low cost, wide application, safety and reliability.
