摘要
文章在弹性地基梁法的基础上,考虑了支撑-围护结构-土体相互作用的过程,假设了更合理的温度变化引起的围护结构变形形式;基于winkler地基梁模型,建立了改进的多层支撑温度变化引起的轴力简化计算方法。算例分析结果表明,本计算方法误差更小,迭代次数更少,更加便于应用于实际。
Using the beam-on-elastic-foundation approach, the process of the brace-pile-soil interaction was considered assuming reasonable enclosure strut deformation caused by temperature fluctuations. Based on the Winkler foundation model, an improved and simplified temperature stress of multi-layer struts was found. The examples show that this method is characterized by relatively few errors and iteration numbers.
