摘　　要：回弹法是检测砌体结构中砌筑砂浆强度的一种常用方法,具有测试快速、操作简便等特点。结合试验研究与工程实践,讨论了采用回弹法检测砌筑砂浆强度时存在的测位回弹点数量偏少、回弹点选择及回弹数据取舍没有统一标准等问题,分析了上述问题对砌筑砂浆强度推定结果的影响,并提出了增加测位内回弹点数量等改进建议,以期为回弹法检测砌筑砂浆强度的工程应用及相关规程修订提供参考。Rebound method is a common used method to test masonry mortar compression strength, with rapid measurement, simple operation and other characteristics. Combined with the experimental research and engineering practice, some problems about rebound method in testing masonry mortar strength were discussed, such as the quantity of rebound points in one testing area may be few, and there is no uniform standard for rebound point selection and rebound data choice. The influence of above mentioned questions on the mortar strength presumption was analyzed. Improvement suggestions such as increasing rebound point quantity in one testing area were put forward in order to provide reference for the engineering application and for the further revision of relative standard.
