摘　　要：本文分析了测点间距、竖向荷裁以及砂浆粘结对砖块回弹值的影响,通过18组试件的对比试 验研究了现场条件下砖块的回弹值与试验室标准条件下砖块回弹值之间的相关关系。根据参数分析和 试验结果,提出了既有砌体结构中砖块强度的现场回弹检测法。In this paper, influence of parameters, such as interval between testing points, vertical load and bond of mortar, on the rebound value of the testing brick is analysed. And an in situ rebound testing method for the strength inspection of fired common brick in existing building masonry structures is proposed based on the results of parameter analysis and the test for 1.8 groups of brick specimens.
