摘要
附加质量法是应用于大坝堆石体碾压质量的重要检测方法,其现场测试参数设置是否合理,直接影响附加质量法检测数据的质量。为了获取现场测试参数,在双江口水电站大坝堆石料区选取了质量块直径、炮检距、震源高度等测试参数进行现场试验研究,通过对附加质量法数据采集、处理与分析全过程中间成果进行分析评价,确定了质量块直径为50 cm、震源高度为35 cm、炮检距为25 cm的现场测试参数,形成了一套测试参数的现场确定方法。
The additive mass method is a crucial detection technique for assessing the rolling quality of rock-fill of dams.The quality of additive mass method’s detection data is directly dependent on the reasonableness of its field test parameters.To determine the optimal test parameters,field tests were conducted in the rock-fill area of the dam of Shuangjiangkou hydropower station.Test parameters,including mass block diameter,offset,and source height,were selected for the field test.Through the analysis and evaluation of the additive mass method data and intermediate results in the data acquisition process,the field optimal test parameters were determined to be a mass block diameter of 50 cm,a source height of 35 cm,and an offset of 25 cm.Consequently,a comprehensive set of field determination method for the test parameters was established.
