- Abstract
In order to research the influence of underpinning pile foundation after excavating tunnel with shield construction, the three-dimensional numerical simulation is carried out by using FLAC 3D based on the actual project in Shenzhen. Different finite difference models are established respectively by changing the sequence of overlapping tunnel excavation, the spacing of the overlapped tunnel, the diameter and length of the pile. Then the data of the settlement of the pile foundation are obtained and the results of influences are analyzed.
