摘　　要：山东省黄河冲洪积粉土地层分布广泛,对该区域工程建设影响较大。本文结合工程实际,对比了室内试验与原位测试在划分粉土密实度上的可靠性,证明了利用原位测试试验在确定粉土密实度上具有更高的准确性,并且也证实了不同原位测试手段得到的试验数据具有高度相关性。在此基础上,研究了剪切波速测试在划分粉土密实度中的应用,并根据剪切波速与常规原位测试试验数据之间的关系方程,推导了剪切波速划分粉土密实度的标准。通过对比可知,根据剪切波速划分的粉土密实度结果与实际情况基本一致。The Yellow river alluvial silt layer in Shandong province is widely distributed and has a significant impact on engineering construction in the region.This paper combines engineering practice and compares the reliability of indoor testing and in-situ testing in dividing the compactness of silt.It proves that using in-situ testing has higher accuracy in determining the compactness of silt,and confirms that the test data obtained by different in-situ testing methods are highly correlated.On this basis,the application of shear wave velocity testing in dividing the compactness of silt was studied,and the standard for dividing the compactness of silt by shear wave velocity was derived based on the relationship equation between shear wave velocity and conventional in-situ testing data.Through comparison,it can be seen that the silt compactness results classified based on shear wave velocity are basically consistent with the actual situation.
