Analysis on the relationship between the SPT number and mechanicalparameters of reticulated laterite in Jiujiang City

Abstract:

In this paper, the correlation analysis between the measured standard penetration test （SPT） number and the depth of the test hole, the compression modulus and the shear strength of the reticulated laterite in Jiujiang City was carried out. The analysis results showed that the SPT number of the reticulated laterite is positively and significant linearly correlated with the test hole depth, positively and weakly linearly correlated with the compression modulus of the soil, positively and weakly correlated with the shear strength of the soil. The analysis results provide good guidance and reference for geotechnical engineering survey activities in Jiujiang.
