为研究大跨度空间拱结构基础的简化设计方法,建立了预应力拉杆这种最常见基础形式的内力分析模型,提出考虑上部结构与基础间相互作用的内力计算方法。以上、下部结构共同作用的分析模型为依据,明确设计的基本要求与主要步骤,给出设计各阶段相应的计算公式,完善了整个设计流程。为大跨度空间拱结构的基础设计提供快速简便的理论指导和技术支持。
In order to study the simplified design method of large-span spatial arch structure foundation, the most common basic form of internal force analysis model of prestressed tension bar is established and the internal force calculation method considering the interaction between superstructure and foundation is proposed. Above and below the structure of the common role of the analysis model as a basis for a clear design of the basic requirements and the main steps are given corresponding design of the various stages of the formula and improve the entire design process. It provides fast and simple theoretical guidance and technical support for the basic design of long-span space arch structure.
