厦门港区粘性土内摩擦角与其它物理指标相关性分析

Analyses on Correlation between Internal Friction Angle and Other Physical Indexes of Cohesive Soil in Xiamen Port Area

通过对厦门港区60个不同位置的土样的室内土工试验成果的参数分析,计算有效应力指标内摩擦角?'与饱和度、孔隙比、塑性指数、液性指数等物理指标之间的相关系数。结果表明:饱和度与内摩擦角之间的相关性较弱,孔隙比、塑性指数、液性指数与内摩擦角之间均具有较强的相关性,其中,孔隙比与内摩擦角的相关性最强,相关系数为-0.828。

Through the analysis on the parameters from laboratory tests on 60 soil samples from different locations of Xiamen Port, the correlation coefficients between the internal friction angles and the physical indexes such as saturation, porosity ratio, plasticity index and liquid index are calculated. The results have shown that the correlation between saturation and internal friction angle is weak, and the correlation between internal friction angle and porosity ratio, plasticity index, liquid index are strong. Among them, the correlation between the void ratio and the internal friction angle is the strongest, and the correlation coefficient is-0.828.
