由于结构裂缝的出现与结构的温度应力、混凝土的收缩、徐变及其构造有直接关系,通过具体工程实践及理论分析混凝土的极限拉伸及温度应力的关系,提出如何用普通方法及措施(设计上、材料上及施工方面)去提高混凝土的极限拉伸,减少混凝土的收缩,达到结构超长不设缝的效果,以节省工程造价及缩短施工工期。 Because the appearance of structural cracks is directly related to the temperature stress of the structure, the shrinkage and creep of concrete, and the structure of concrete, the relationship between ultimate tensile stress and temperature stress of concrete is analyzed through concrete engineering practice and theory, and how to use ordinary methods and measures Design, materials and construction) to improve the ultimate tensile concrete, concrete shrink to reduce the length of the structure to achieve seamless effect, in order to save construction costs and shorten the construction period.
