The Finite Element Analysis of the Deep Foundation Pit Excavation and the Model Test
The fracture theory of soil was a new developing problem in recent year. In this paper, the basic principle of fracture mechanics and the strength theory of soil were combined, and the soil-cracking strength theory was adopted to build a constitutive relation for cracked soils. In order to use such theory and to analyze how the cracked soils effect on retaining structure, we developed an elastoplastic finite element program. Finally, the calculation results from this program were compared with the surveying measured in model testing.
