摘要

摘要: 桩锚支护结构在基坑支护中已有广泛应用,在同一个基坑中采用单排+预应力桩锚及双排桩+预应力锚索支护形式,结合现场实际监测成果,分析基坑变形性状以及对周边建筑物变形的影响,同时阐述锚索施工对基坑及周边建筑的影响,分析基坑变形的水平影响范围。

Abstract: The pile-anchor supporting structures have been widely used in deep foundation pits. The supporting structures of single pile-anchor and double-row piles are used in the same deep foundation pit. The influence of deformation behaviors of the excavation and adjacent buildings are analyzed based on the monitoring results. The influence on the adjacent buildings is also described because of construction of anchor cables. In addition, the influence scope of horizontal deformation of the excavation is analyzed.
