随着经济的不断发展,国家基础工程的建设项目越来越多,加之去产能以及加大投资等国家战略的影响,可以说当前我国处在一个“大兴土木”时代。基坑在大量建筑工程中有大量的应用,基坑围护结构对于构筑物基础的修建、施工过程中的安全保证以及今后构筑物的正常使用都有着重要的意义,由此可见基坑以及基坑围护结构对于建筑工程的重要性。锚杆也是工程建设中常用的材料,锚杆在以矿山法隧道为代表的一系列工程中大量应用,因其施工简便、成本较低、可靠性高,在基坑围护结构中大量使用。预应力锚杆的出现大大提升了锚杆的应用效果,对工程增加了一定的安全性与可靠度,成为当前广泛研究的课题,本文对预应力锚杆在基坑围护中的应用展开研究。
With the constant development of economy and the increasing number of national infrastructure projects, coupled with the impact of national strategies such as going to production capacity and increasing investment, it can be said that our country is now in an era of “rejuvenating the environment.” The foundation pit has a large number of applications in a large number of construction projects. The foundation pit enclosure structure is of great significance to the construction of the foundation of the structure, the safety assurance in the construction process and the normal use of the future structures. Thus, it can be seen that the foundation pit and the foundation pit The importance of retaining structure to the construction. Bolting is also commonly used in engineering construction. Bolts are widely used in a series of projects represented by the Mines and Tunnels. Due to their simple construction, low cost and high reliability, they are widely used in retaining structures of foundation pit. The appearance of prestressed anchor rod greatly enhances the application effect of anchor rod, adds some safety and reliability to the project, and becomes the subject of extensive research at present. This paper studies the application of prestressed anchor rod in foundation pit enclosure .
