Abstract: Based on project of state-owned enterprises base in Shanghai Expo B zone, three sets of uplift pile were tested before and after pit excavation, and the site tests were simulated by finite element software ANSYS and MIDAS GTS. Variation characteristics of uplift capacity under deep pit excavation were research furtherly.
Keywords: deep pit excavation; uplift pile; soil rebound; ultimate uplift capacity; finite element method
