随着城市建设规模逐渐增大,基坑工程设计逐步向开挖深度大、周边环境复杂、工程地质水文地质条件复杂的方向转变,这对设计人员提出了更高的要求。本文基于大连市某档案中心基坑边坡支护工程,讨论了复杂环境下,支护桩预应力锚杆支护型式应用在在基坑支护和边坡支护中的问题,为今后的工作得出一些结论和启示。 With the gradual increase of urban construction scale, the design of foundation pit gradually changes to the direction of deep excavation, complex surrounding environment and complex geological and hydrogeological conditions, which puts forward higher requirements on designers. Based on the foundation pit slope supporting project of a file center in Dalian, this paper discusses the application of the prestressed bolt supporting type of supporting piles in the support of foundation pit and slope supporting in complex environment. In the future, Work to draw some conclusions and inspiration.
