1 前言关于钢筋混凝土构筑物的裂缝控制理论和设计施工经验,已发表不少论文。王铁梦在他的专著中,主要从普通混凝土的收缩变形和温差变形这两个主要矛盾开展分析计算,提出对混凝土裂缝控制的有效设计和施工措施。他还提出取消伸缩缝的理论和实践依据,以及“抗”与“放”的原则。吴中伟教授在他的专著中,提出用膨胀混凝土补偿收缩的理论,采用积极的“抗”的办法,可有效地控制混凝土的裂缝。 1 Introduction The theory of crack control and design and construction experience for reinforced concrete structures has published many papers. In his monograph, Wang Tiemeng mainly analyzes and calculates the main contradictions of shrinkage deformation and temperature difference deformation of ordinary concrete, and proposes effective design and construction measures for concrete crack control. He also proposed the theoretical and practical basis for canceling expansion joints, and the principles of “resistance” and “release.” In his monograph, Prof. Wu Zhongwei proposed the theory of compensating shrinkage with expansive concrete, and adopting a positive “resistance” method to effectively control concrete cracks.
