    Abstract
  • The engineering geological conditions of a large area deep foundation pit in Ningbo are complex, and the deformation control is difficult. According to the excavation process and section characteristics of the foundation pit, pile-anchor and pile-braced composite supporting structures were adopted in the foundation pit, and the supporting structure of gravity retaining wall plus slope were used at the junction of different basement development sites. Combined with the monitoring data of the foundation pit, the excavation process of the foundation pit was analyzed, and the internal force and deformation control effect of different anchor cable types were mainly discussed. The practice of this project can provide reference for similar projects.
