摘　　要：套筒内灌浆料的抗压强度是影响节点连接性能的关键因素之一,现场难以准确测量该参数。分析对比了现有检测方法的优缺点,阐明了表面硬度法的独特优势以及缺乏工程验证的不足,并依据已建立的测强曲线,开展了实际工程验证。结果表明,对于所抽检的6个剪力墙,表面硬度法与同条件试件法检测结果的相对误差较小,为5.55%~10.79%,结果可靠性较好;同时,从应用过程中提炼了该方法现场操作的主要步骤,可供工程检测人员参考。The compressive strength of the grouting material in the sleeve is one of the key factors affecting the joint performance. It is difficult to messure the parameters accurately on site. This paper analyzed the advantages and disadvantages of existing detection methods, described the unique advantages of surface hardness method and its need of engineering verification, and according to the established strength curve, the application of practical engineering is verified. The results in the samples show that the relative error between the test results by surface hardness method and the specimens under the same conditions is small, ranging from 7.74% to 10.79%. At the same time, the main steps of the field operation of the method are extracted from the application process, which can be used as a reference for engineering inspection personnel.
