Numerical study of dewatering in a large deep foundation pit

Environmental Earth Sciences, 2012
During foundation pit excavation, groundwater is often the most important factor that affects pit stability. Dewatering is widely used in pit excavation to avoid uplift of excavation floors due to high water pressure. The characteristics of seepage in small-scale deep foundation pits of high-rise buildings or in the long narrow foundation pits of ...

Influence of Deep Foundation Pit Construction to the Surrounding Buildings - Take a Foundation Pit in Haikou as Example

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 ...

Analysis of Surveillance for Deep Foundation Pit of Subway Station

Applied Mechanics and Materials, 2012
Deep foundation pit of subway station project are affected by the geological conditions with rich water and sand seriously. So the construction has a greater difficulty. We have to analyze the measured data and study on the deformation law of retaining structure and soil. That can be used as theoretical verification about the design scheme of retaining
