中文摘要:针对九江市网纹红土层标准贯入试验实测锤击数与试验孔深、土的压缩模量、抗剪强度关系之间进行了相关性分析。结果表明:网纹红土标准贯入击数与试验孔深为正显著线性相关关系,与土的压缩模量为正弱线性相关关系,与抗剪强度为正弱线性相关关系。分析成果对在九江市开展岩土工程勘察活动具有很好的指导和借鉴意义。

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.
