The Review of Research on Deep Foundation Pit Excavation under Unloading Condition

Article Preview

Abstract:

The calculation parameters of foundation pit excavation are usually obtained by the conventional triaxial test regardless of the unloading process, which leads to supporting mobile,soil rebound caused by excavation unloading, and unreasonable and dangerous design. In recent years, some researches have been done on pit excavation under unloading condition. In this paper, a review on pit under excavation unloading according recent research was made including stress path tests, numerical simulation, and constitutive model.
