摘要
沈阳地铁2号线南延线起点区间盾构井,其结构受力具有典型的空间特性,目前常用的平面框架模型在准确性及精度上给设计带来一定的偏差。文章建立了空间结构模型,对其进行整体受力计算分析,并对其框架梁、墙、柱等重要组成构件,在施工和使用阶段的受力特性进行深入对比和分析,提出了各结构构件在不同设计阶段的要点,对本区间盾构井结构进行了更经济、合理的设计。
A special structure model is built in this paper to carry out the entire stress calculation and analysis as well as the comparison and analysis of the stress properties of major components such as frame beam,wall and pillars during construction and operation period.The paper proposes some key points for each component for different design stages and provides an optimized and cost-effective design.
