预应力锚索在深基坑支护中的应用

Application of the prestressed anchor cable in the deep foundation pit support

结合某工程概况、工程地质及水文条件,介绍了基坑周边环境复杂状况下采用的锚索护坡支护体系,以及多层预应力土锚索的应用,对预应力锚索施工、锚杆拉力试验及基坑变形观测进行了论述,最后指出该支护体系的可行性。

Combined with the engineering situation, the geology and hydrological conditions of the engineering, the paper introduces the anchor slope protection support system under the complex environment around the foundation pit and the application of the multilayer prestressed soil anchor, discusses the construction of the prestressed anchor cable, the anchor pull experiment and the foundation pit deformation observation, finally points out the feasibility of the support system.
