【摘要】 水泥混凝土徐变是在持续应力作用下混凝土应变的增加,而这种应变的增加比瞬时弹性变形大1~3倍,所以徐变对混凝土的结构性能有相当重要的影响。在总结和借鉴前人研究成果的基础上,结合笔者对混凝土徐变的研究和认识,从内部因素和外部因素两个大的方面阐述了影响水泥混凝土徐变的作用机理。更多还原

【Abstract】 Concrete creep is a kind of phenomenon of concrete strain when the continuing stress is forced on concrete components,the increasing of the strain is so large that it is one to three times larger than the instantaneous elastic deformation,so the creep plays an important role in the capabilities of concrete structures.Based on the research results from predecessors,the acting mechanism of influencing the creep of concrete is discussed in two aspects as both internal factor and external factor.更多还原
