Research on Creep Model of Loess Considering Construction of Underground Warehouse in China

Abstract:

Drucker-Prager Creep Model is introduced, and the Viscoelasto-Plastic Model with Double Yield Surface is detailed deduced. Parameters of loess in China West are discussed in detail during construction of underground warehouse. Those two creep models are applied to pit excavation during construction of underground warehouse. The results calculated show that the displacements calculated according to Viscoelasto-Plastic Model with Double Yield Surface is bigger than those according to Drucker-Prager Creep Model. Those ways uesd may provide reference to engineering practice.
