北京地区回弹法、超声回弹综合法检测混凝土强度的曲线修订

摘要

现行的北京地区《回弹法、超声回弹综合法检测泵送混凝土抗压强度技术规程》[1](DBJ/T 01-78-2003)已不能较好地适应于目前北京地区的混凝土实际情况,为此亟需对测强曲线进行修订.论文对本次修订工作的技术路线、修订方案、回归分析、修订结果及验证工作等方面进行了全面介绍,供相关技术人员参考.%Rebound method and Ultrasonic-rebound combined method are very common non-destructive test method for concrete compressive strength. The current standard of Beijing,DBJ/T01-78-2003,Technical Specification for Inspection of Pumped Concrete Compressive Strength by Rebound Method or Ultrasonic-Rebound Combined Method,has not better applied to actual concrete conditions in Beijing region anymore, so it is very urgently necessary to revise the curve for concrete strength inspection. This paper comprehensively introduces technical route,revision scheme,regression analysis,revision result, verification,etc.,which are references for related technicians.
