摘要
从内部因素和外部因素两个方面综合论述了国内外有关混凝土拉伸徐变的研究现状,总结和评述了混凝土拉伸徐变研究的主要成果。对比了各个影响因素对拉伸徐变和压缩徐变影响,并提出了对水胶比、加载应力的水平和掺加硅粉对混凝土拉伸徐变的影响需要进行进一步的研究。
In this paper study situation of concrete tensile creep home and abroad is reviewed. The influencing factors of concrete tensile creep are comprehensively analyzed in two aspects as both internal factor and external factor. Based on these analyses, the main results on concrete tensile creep are summarized and analyzed. A comparison was conducted between the influence to the tensile creep and compression creep. And further investigation of the influencing of water binder ratio, applied stress level and adding silica fume to the tensile creep is needed.
