Abstract

Taking a deep and large foundation pit project as an example, the paper analyzed some developmental characteristics of its deformation during construction. The deformation included vertical displacements of the ground surface and horizontal displacements of deep soil surrounding the foundation pit. At the same time, the trends of the ground settlement were predicted based on the monitoring data. The analysis and predictions showed that: (1) The soil around the foundation pit was influenced by the excavation and supporting construction; (2) The vertical and horizontal displacements appeared some regular patterns of gradual development over time. In addition, there were certain differences in the trends of measuring points at different locations; (3) By fitting the monitoring data, the deformation of the foundation pit could be effectively predicted and offer a guidance to the engineering practice.
