不同测定方法的液限值相关关系分析与应用. (Chinese)

At present, the cone method is used to determine the liquid limit in China, while the dish type method is mostly used in the world. The theoretical analysis and test results show that the 17 mm liquid limit of 76 g cone is equivalent to that measured by the dish type liquid limit instrument represented by ASTM D423 standard. Therefore, by establishing the correlation between 10 mm liquid limit and 17 mm liquid limit of cone method, the correlation between 10 mm liquid limit of 76 g cone and liquid limit of dish type method was indirectly analyzed. Based on this, the connection relationship between domestic and international standard liquid limit test is established to guide domestic technicians to analyze and evaluate foreign geotechnical data by using rich domestic experience, so as to deepen the understanding of the physical and mechanical properties of foundation soil of foreign projects. The geotechnical parameters determined on this basis can provide reference for international engineering design. [ABSTRACT FROM AUTHOR]

目前我国测定液限的方法是采用圆锥仪法，而国际上多采用碟式仪法。理论分析及试验结果表明，76 g 圆 锥的 17 mm 液限与以美国 ASTM D423 标准为代表的碟式液限仪测得的液限基本相当。为此，通过建立圆锥仪法的 10 mm 液限与 17 mm 液限的相关关系，进而间接分析 76 g 圆锥 10 mm 液限与碟式仪法液限的相关性。据此建立国内 与国际标准液限试验的衔接关系，指导国内技术人员，应用丰富的国内经验，分析与评价国外岩土数据资料，加深 对国外项目地基土物理力学特性的认识，据此确定的岩土参数可以为国际工程设计提供参考。 [ABSTRACT FROM AUTHOR]
