    Abstract
  • Based on the asymmetric excavation project adjacent to an existing shallow foundation building in Changsha, the proposed study used the finite difference numerical program to establish numerical models that considers the interaction between the structural foundation and the ground. Through the numerical simulation method, the influence of different excavation schemes on the ground deformation, the deformation and force of existing buildings has been analyzed. Numerical analysis results show that the existence of shallow foundation building affects the settlement curve of the ground surface caused by excavations. The asymmetric excavation sequence has an important influence on ground deformation and structural forces of adjacent existing buildings. Taking into account the construction conditions and the impact of excavations on the deformation of the ground and buildings, priority should be given to the excavation of the foundation pit on the far side of the existing building, and then the foundation pit excavation on the near side.
