The simulative analysis with the Mohr-Coulomb model of FLAC3D program is carried out based on the development of deformation for foundation pits of a high-rise building in Beijing. Comparing with the results of the in-situ monitoring
the deformation
collapse and support for the foundation pits are discussed. It can be shown that the Mohr-Coulomb model of the FLAC3D program can be used to simulate the foundation excavation and the collapse and the slope support very conveniently and accurately. The results obtained are safe and reliable. The FLAC3D program can be widely used in the simulation of foundation pits.
