Analysis of Monitoring Results of a Deep Foundation Pit with Pile-Anchor Retaining Structure
According to characteristics and surrounding environments of a deep foundation pit with pile-anchor retaining structure, a monitoring program was developed. The monitoring focused on horizontal displacements of retaining piles, subsidence of soil surrounding foundation pit and settlements of buildings near foundation pit. The results show that the maximum displacements are in middle position of sides and at corners of foundation pit. The horizontal displacements and settlements of pits are efficiently rejected by anchors. The displacements of buildings near foundation pit are affected by many factors, such as the excavation speed and anchor. The displacement exists characteristics of time and spatial effects. The monitoring results provide a reliable basis for the safety construction and rational organization of construction.
