土的物理力学与工程特性指标分析

Analysis for Physical and Mechanical Indexes and Engineering Caracteristical Indexes of Soil

岩土工程材料具有独特性,与其它建筑材料存有显著的不同,笔者在结合岩土工程实践工作和参考相关文献资料的基础上,对土的物理力学指标进行了分析,研究了各个指标间的联系和相关性、可靠性,从中找出一些共性特征,进而分析其工程特性指标,并对工程特性指标的测试方法进行阐述。研究成果对于推动岩土工程设计从安全度控制向概率控制和岩土工程可靠性研究具有一定的参考意义。

Geotechnical engineering material is unique,and has the significant differences compared with other building materials.On the basis of geotechnical engineering practice and reference to relevant literature,the physical and mechanical indexes of soil are analyzed here,the linkages between the various indicators and relativity as well as reliability are preliminarily studied,some common characteristics are found out,still further their engineering characteristical indexes are analyzed,and the test methods of engineering characteristical indexes are described,which would promote the geotechnical engineering design from the safety control to the probability control and the reliability research on the geotechnical engineering.
