摘　　要：近年来,附加质量法已逐步应用于堆石体碾压密度无损检测中。基于现有研究成果,考虑检波器主频、激振锤落距、激振锤偏移距、附加质量大小、附加质量级数5个测试因素,在河南新华五岳抽水蓄能电站上水库主堆石料和过渡料上分别进行了附加质量法测试影响因素试验。结果表明:堆石料颗粒粒径变化对附加质量法测试参数的选择影响较大,这主要与堆石料的岩性、级配、刚度有关,为提高附加质量法测试的可靠性,在进行附加质量法测试前,应首先在测试堆石体上进行附加质量法参数标定试验。In recent years,the additional mass method has been gradually applied to nondestructive testing of the compacted density of rockfill.Based on existing research results,it conducted an additional mass method impact factor test on the main rockfill material and transition material of the upper reservoir of Henan Xinhua Wuyue Pumped Storage Power Station by taking into account the five test factors of the dominant frequency of the geophone,the drop distance and offset distance of the hammer,the magnitude of the additional mass and the levels of the additional mass.The test results show that the particle size change of the rockfill material has a significant impact on the selection of the additional mass method test parameters,This is mainly related to the lithology,grading,and stiffness of the rockfill.In order to improve the reliability of the additional mass method,before conducting the additional mass method test,it is necessary to first conduct the additional mass method parameter calibration test on the test rockfill.
