Abstract
In water-rich area, foundation pit pum** has adverse effects on adjacent buildings. In this study, a series of numerical simulations are carried out, based on a practical dewatering test in an excavation for metro station in Tian**, to investigate the characteristics of near building pile deformations induced by dewatering. The effect of different pum** depth (Hd) on the pile axial force and lateral friction are revealed. The results indicate that the axial force of the pile foundation experiences a substantial increment; accordingly, the pile shaft resistance becomes negative in the same depth range, and the neutral point appears at the position of 1/2 times the pile length from the pile crown. The research results can provide guidance to the safety assessment of the existing building pile during pum** of adjacent foundation pit.
