Study On Impact Of Buildings Near The Deep Station Foundation Pit Engineering

With the rapid development of the urbanization，the subway became the veryimportant way to solve traffic problem in major cities. The deep station foundationengineerings generally are constructed in the center of the city, the constr uctionenvironmental science is very complex and the place is not broad. There are manyhigh-rise buildings near the deep station foundation engineering. So structureengineers not only have to consider the security of the foundation pit engineering butalso study on impact of buildings near the deep station foundation pit engineering.This can protect the buildings and avoid damage.This article analyzes and sums up the deep excavation engineering deformationtheory. The project local geotechnical engineering geological reconnaissance, On theneed to study the foundantion excavation of subway station and the adjoining buildingto the analysis of the situation. numerical simulation research provided. Withoutconsidering groundwater conditions, Pit, supporting structure and adjacent buildingsin a system study, we use large-scale engineering software FLAC3D, the wholeprocess of soil reinforcement, deep excavation and retaining was NumericalSimulated. By comparing simulation analysis of influence of adjacent structures in thesurrounding soil reinforcement excavation of foundation pit order, we summed upduring excavation influence of the adjacent buildings, optimized structure excavationsteps order. Near the building to take reinforcement measures provide a reference.This study provides a reference for the actual pit design and construction of economicrationality and guiding significance.
