Monitoring and analysis of excavation based on supporting structures of double-row piles and prestressed anchor cables

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.
