Abstract:Structural design on complex sites is often affected by slope support. Taking the basement of a project as anexample, due to reasons such as insufficient red line distance avoidance, it is necessary to consider the horizontal force ofthe basement structure to withstand the slope support structure. The relationship between the building and the surroundingsite topography and the general situation of the project were introduced. Considering the horizontal thrust of the slope, thesynergistic force between the slope and the basement structure was analyzed. The force transmission path of the structure,the requirements of the structure layout, the basic calculation assumptions, the force conditions of the basement structureand the foundation, and the calculation results were expounded. The results show that the calculation assumptions areconsistent with the calculation results, the force of whole structure is reliable and can meet the requirements. Consideringthe top-down method, the analysis of the construction simulation was carried out, which further demonstrates the reliabilityof the synergistic force of the basement structure and the slope support.

Keywords: basement structure; slope support; synergistic force; force transmission path; top-down method;construction simulation
