Abstract

Differential settlement of raft foundation for super high-rise buildings easily leads to adverse effects such as concrete cracking, deformation of pre-buried pipelines, and tilting of the building, but the current settlement theory and analysis methods are still difficult to simulate the change rule of actual foundation settlement. In this paper, in order to better consider the interaction effect of foundation soil, raft foundation and superstructure, a raft foundation monitoring scheme is established according to a super high-rise building project, and direct observation of on-site soil pressure, pore water pressure, internal force of the raft reinforcement and settlement of the raft is carried out. The monitoring data indicates that the soil pressure can show the stress unevenness of the foundation soil. The internal force of the raft reinforcement is closely related to the vertical load of superstructure, and has an exponential function relationship with the size of the settlement. The soil pressure, pore water pressure, and reinforcement stress can be measured by the automatic monitoring system in the whole process of the construction to ensure that there is no large force variation in the construction process. The settlement difference of raft foundation for the super high-rise structure in this paper is mainly affected by the early concrete creep, and its own gravity is the second influence factor.
