摘要
岩块颗粒密度是建筑材料选择、岩石风化研究、岩体稳定性分析等必须的重要参数,目前测定方法采用比重瓶法和水中称量法。为了探求两种方法的差异,进行了对比试验,得出了两种测试结果都满足要求,水中称量法的结果略小。同时从样品制备和操作过程分析两种方法的优点和局限性,发现水中称量法更方便快捷。
The particle density of rock block is an important parameter necessary for the selection of building materials,the study of rock weathering,and the stability analysis of rock mass.At present,the pyknometer method and in-water weighing method are used for the determination.In order to explore the difference between the two methods,a comparative test was carried out.The results show that the two test results met the requirements,and the result of in-water weighing method was slightly smaller.At the same time,compared with the advantages and limitations of the two methods from the sample preparation and operation process,the in-water weighing method is more convenient and fast.
