    Abstract
  • A large-scale construction project needs to mound soil over a large area on the constructed foundation pile due to the change of excavation conditions. Large-area mounded soil will cause the settlement of group foundation piles. After the excavation of foundation trench, the settlement of foundation piles is discrete, and the maximum settlement of foundation piles is as high as 670 mm, the maximum extreme value of settlement between foundation piles in single buildings is as high as 510 mm, which far exceeds the standard calculation value, thus the settlement attribution is controversial. Using the finite element software PLAXIS3D, a three-dimensional numerical model was set up and comprehensive analysis of pile settlement was carried out. The results show that large area soil mounded above the completed pile foundation can cause large settlement of the foundation pile. Maximum settlement of ground surface and pile top are located at the center of the mounded soil, negative friction of two piles with maximum and minimum settlement is doubled; According to regional analysis, the overall settlement trend of pile caused by large area disorderly mounded soil conforms to the settlement law in soft soil area; The main factors of large dispersion of each foundation pile include: the height, area and time of the mounded soil, drainage conditions, soil layer conditions of pile crossing, soil layer conditions of underlying layer at pile end, etc. This research has accumulated experience for similar projects.
