摘要：

The paper discusses the influence of a group of high-rise buildings on land subsidence, based on a modeling exercise. The model consisted of five layers of soils typical of the Shanghai area, with the buildings placed on piles set in the upper silty sand horizon. It was loaded to represent the construction sequence of the four buildings. The main settlement was observed to be in the underlying clayey layer. The model demonstrated the increase in pore water pressure with staged loading, its effect on deformation and the increase in effective stress over time. It indicated the largest amount of settlement over time occurs between the buildings.
