摘　　要：为提高回弹法开展混凝土强度表征和原位测试的准确性,针对回弹法统一测强曲线在地域性差异、原材料波动、配合比变化等情况下的不适用性,分析了回弹法测强曲线的发展趋势;据此从原材料和配合比两个方面对测强曲线的影响因素进行了系统分析,并对进一步研究做出了展望。In order to improve the accuracy of strength characterization and in situ test of concrete,the development trend of testing strength curve of rebound method was analyzed,which was used to respond to the inapplicability of the national testing strength curve of rebound method because of the variations of region,raw materials and mixture proportions.After that,the influencing factors of testing strength curve were analyzed from two aspects of raw materials and mixture proportions.And the prospect of further research was also made.
