Study on Earth Pressure of Foundation Pit Excavation by Model Test

Advanced Materials Research, 2011
As there are more and more high-rise buildings in the big cities, some new foundation pits are usually near old high-rise construction. In this case, foundation pit excavation is an engineering problem which needs to be solved urgently. This paper aims at the problem where the new foundation pit is closing to a high-rise building with a cement fly-ash ...

Influence of Foundation Pit Excavation on Adjacent Railways and Strengthening Measures

Advanced Materials Research, 2013
The excavation of foundation pits near existing railway will cause innegligible deformation for the railway line. This paper first conducts numerical simulation for the impact of the excavation of foundation pit for a building close to existing railway lines on the deformation of the railway, and arrives at such conclusions: the excavation of ...

Study on Effects of Ground Deformation Based on Foundation Pit Excavation

Advanced Materials Research, 2013
With the continuous development of urban underground space, the environmental effects of foundation pit excavation have been paid extensive close attention. Unfortunately, there are few researches in mucky soil and peaty soil. Adopted the software of FLAC-3D, the ground deformation due to the foundation pit excavation is simulated.
