Influence of the Dynamic Excavation Construction Procession Rail Transit Projects in Deep and Large Foundation Pits

Abstract:

In the construction of high-rise buildings, the effect produced by the excavation of deep and large foundition pits on the surrounding structures cannot be ignored. This paper presents a case study from a construction project located in Nanjing, in which the dynamic excavation process of a founditon pits is numerically analyzed with finite element method on Plaxis. The impact of various excavation stage on subway tunnel nearby is achieved in terms of the results of data analyses and assessments.
