Abstract

The excavation depth of foundation pits in modern urban high-rise buildings and underground engineering is getting larger and deeper, and the shape of the foundation pits is more complicated due to the surrounding environment. At the same time, the foundation pit construction in seasonal frozen soil areas is still facing the freezing and thawing effect during winter. It affects the stress and deformation deformation of the foundation pit and the supporting structure, and even cause the foundation pit to be unstable. Thermodynamic coupling numerical analysis model considering the influence of freezing and thawing in the background of the second stage foundation pit engineering of Shenyang Dongsen CBD Business Plaza was established in the paper, through the controls of temperature parameter to simulate the temperature change process under different working conditions, revealing the temperature effects on the foundation pit and the internal force and deformation law of the foundation pit. It has certain application value and reference significance for guiding the practice of foundation pit engineering in seasonal frozen soil areas.
