摘要:在复杂场地上进行结构设计,常会受到边坡支护的影响。以某项目地下室为例,由于红线距离避让不足等原因,需要考虑地下室结构承受边坡支护结构的水平力。介绍了建筑和周边场地地形的关系以及工程概况;考虑边坡水平推力作用,分析了边坡和地下室结构的协同受力。阐述了结构的传力路径、结构布置要求、基本计算假定、地下室结构和基础的受力情况以及计算结果。结果表明,计算假定与计算结果相吻合,整个结构受力可靠,可以满足要求。考虑逆作法,进行了施工阶段分析,进一步论证了地下室结构和边坡支护协同受力的可靠性。

Abstract: Structural design on complex sites is often affected by slope support. Taking the basement of a project as an example, due to reasons such as insufficient red line distance avoidance, it is necessary to consider the horizontal force of the basement structure to withstand the slope support structure. The relationship between the building and the surrounding site topography and the general situation of the project were introduced. Considering the horizontal thrust of the slope, the synergistic 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 structure and the foundation, and the calculation results were expounded. The results show that the calculation assumptions are consistent with the calculation results, the force of whole structure is reliable and can meet the requirements. Considering the top-down method, the analysis of the construction simulation was carried out, which further demonstrates the reliability of 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
