摘要
从弹性地基上长条板受力计算模型出发,分析了其温度应力的变化规律,指出温度应力的变化规律可作为判断承台大体积混凝土是否开裂的依据,并给出了施工现场温度裂缝控制的一些建议。
Starting from the mechanical computation model of long-strip slab on elastic foundation, this paper makes the analysis on the changing pattern of its temperature stress, points out that the changing pattern of the temperature stress can be regarded as the evidence for deciding whether or not the mass concrete of bearing platform cracks, and puts forward some suggestions on controlling the temperature cracks on the construction site.
