Numerical Simulation Program of the Foundation Pit
Advanced Materials Research, 2012In 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 ...

Applied Mechanics and Materials, 2012
This paper takes example of a foundation pit in Haikou, analyzing the influence on the surrounding buildings in the course of the excavation depth, daily rainfall, foundation form of the building and other factors. The results show that the excavation depth and strong rainfall may lead large deformation of the surrounding buildings, and the deep ...

Deformation Compatibility Control Technique for Foundation Pits
2016Foundation pits also involve large amount of underground excavations, which are somehow similar to the tunneling sequences. Foundation pits instability not only poses dangers to the projects themselves but also puts the surrounding buildings or facilities at risk.

Stability of Submarine Foundation Pits Under Wave Loads
Volume 4: Offshore Geotechnics; Ronald W. Yeung Honoring Symposium on Offshore and Ship Hydrodynamics, 2012Shallow foundation structures offer ecological benefits compared to pile foundations as less noise is emitted at sea floor level during construction process. On the other hand, shallow offshore foundations can rarely be placed on top of the sea floor.

The excavation of deep-foundation pit can impact the deformation and stability of adjacent buildings greatly. In this paper, shallow-foundation frame building affected by excavation of the pit, on the condition that the building has formed different angles with the side of the pit, is analyzed by establishing a 3D finite element numerical model.

Foundation Pit Deformation during the Excavation and Simulation
Applied Mechanics and Materials, 2014Based on the background of foundation pit excavation of a village, the process of excavation is simulated by FLAC3D .And the calculation and analysis is combined with the engineering practice. The results show that the deformation of foundation pit is mainly composed of ground surface settlement, and the maximum deformation occurred in the middle of ...
