剪切波速测试在粉土密实度划分中的研究与工程应用OA

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.
