Numerical Simulation Of Deep Foundation Pit Island Excavation

As China’s economic development and population increase, the city’s high-rise,more and more problems will increasingly deep foundation stand out. The other hand,due to urban traffic congestion, many cities have begun construction of subwaywhich inevitably involves the problem of deep excavation. Many are out of deepfoundation and the city’s bustling downtown area, which the foundation design andconstruction put forward higher requirements. In recent years, our country’s deepfoundation of theory and practice has made great progress, but there are still manyproblems.Currently Numerical simulation of deep excavation is a research hotspot. It canbe taken into account during excavation of the many factors that can reflect theproblems that may arise. Most are two-dimensional numerical simulation ofexcavation does not reflect the spatial effect, even three-dimensional model of itsexcavation excavation mostly hierarchical, that each time you dig up the soil and thenproceed to the next step all open digging. Such access to a larger and the actualsituation. This article is based on a three-dimensional excavation Excavation of thecurrent city more popular island Numerical simulation of excavation. Expect to beable to show more real excavation of the entire process. In the simulation took intoaccount the process of dewatering, and soil structure interaction effects excavationspace of time and other factors. And the model parameters are discussed and impactanalysis, and try to inverse the model parameters, and achieved good results. Thepurpose of this paper is the modeling process and discuss various issues whichsimulate the excavation of the entire process, I hope to be able to provide a referenceto the actual project in future calculations and simulations can be used in this way formodeling and parameter adjustment.
