海南后水湾海域浅层粘土的工程地质特性评价

利用后水湾内两口工程地质钻孔，分析了后水湾海域浅层粘土的工程地质特性，对钻孔中各层粘土的物理力学指标进行了统计分析，结果显示：第二层粘土的物理指标的变异性大于其他两层，压缩系数和抗剪强度指标分别与主要的物理状态指标间的相关性呈现相反的特征；研究区浅层粘土的压缩系数与含水率、天然密度、饱和度及孔隙比成较好的线性关系；黏聚力及内摩擦角与含水率、天然密度、孔隙比及液性指数呈曲线相关，以幂函数曲线拟合度最高．

Assessment of Geotechnical Characteristics of Clay in the Houshui Bay,Hainan

In the report, the core samples from the study area were used to analyze the geotechnical characteris- tics of clay and the physical and mechanical indexes of each layer clay. The results indicated that the variability of the second layer clay is higher than that of other two layers, the correlation between compression coefficient, shear strength indexes and their respective physical indexes were reverse; there were good linear correlations be- tween compression coefficient and moisture content, density, saturation and pore ratio; there were curve correla- tions between cohesion and internal friction angle and moisture content, density, saturation, pore ratio and solu- tion index, in which the curve fitting of power function was the highest.
