Numerical Simulation Program of the Foundation Pit
In this paper, a deep foundation pit of one subway station is analyzed under two different precipitation conditions, and the deformation laws of the pit under one-time precipitation and step-by-step precipitation conditions are investigated. The results indicate that the deformations caused by one-time precipitation are significantly larger than the deformations caused by step-by-step precipitation. Therefore, a step-by-step precipitation scheme is preferred in order to reduce the deformation cause by foundation excavation, when construction period permits.
