关于振动法测试碾压混凝土填筑密实程度的研究

About the research of test roller compacted concrete filling compaction degree by vibration method

文章介绍了一种用振动法测试碾压混凝土填筑密实程度的研究过程和成果,提出了用土体振动参数表征密实程度的观点,对土体振动传播速度、主振频率、振动幅度多种参数与密实度的关系进行了探究,发现了振动频率、振动幅度与土体密实程度之间存在的规律,并以此为基础形成了一种新的碾压混凝土密度程度测试方法,有望在业内得以应用。

This paper introduces the research process and result about testing roller compacted concrete filling compaction degree using vibration method, put forward with the view of characterizing soil dense degree by its parameter, and to explore the relationship between a variety of soil vibration parameters and compactness of soil, including the soil vibration propagation speed, the main vibration frequency, the vibration amplitude etc, and to find the rule between the soil vibration frequency, vibration amplitude and soil compaction degree. On this basis, to form the new testing method for density degree of roller compacted concrete, is expected to application in the industry.
