| 摘 要： | 云南大理洱海周缘分布着厚层的早全新世软粘土,大量原状样品的工程性质测试结果表明,洱海东缘早全新世软粘土具有高含水量、孔隙比高、压缩性强、强度低、高塑性等工程特性,其中表层软土超固结现象明显。通过对软土的物理力学指标统计分析表明,洱海东缘软粘土的力学指标的变异系数较大,而物理性质指标变异系数很小;多个物理指标之间及物理指标与力学指标之间存在明显的相关性。对洱海东缘软粘土各类工程特性指标之间相互关系的认识,不仅有助于揭示软粘土的工程性质及其形成机理,而且可以指导软粘土工程问题处理措施的合理选择。 |

| Abstract: | Early Holocene thick soft clay is distributed around Erhai Lake.The results of engineering property tests indicate that the soft clay on the east bank of Erhai Lake has such engineering properties as a high water content,a high porosity ratio,high compressibility,low strength and high plasticity.The phenomenon of over-consolidation is very remarkable.The statistic analysis of physical-mechanical index parameters of soft clay indicates that:the variability coefficient of the mechanical index is high while the variability coefficient of the physical index is low,and the correlations between various physical indices and between the physical index and mechanical index are apparent.Knowledge of the relation between all kinds of indices of various engineering properties of soft clay is not only helpful to revealing the engineering properties and formation mechanism of soft clay,but also instructs us to choose relative measures to solve the engineering problems of soft clay. |
| Keywords: | Early Holocene soft clay engineering property over-consolidation correlation analysis Erhai Lake |
