中/欧/美岩土参数选用简析

Brief Analysis of Selection of Geotechnical Parameters Specified in Chinese, European and American Standards

中欧美岩土勘察体系不同,岩土参数的选用有共性,也有不同。通过分析中欧美不同体系下的岩土参数选用方法、标准,总结了中欧美岩土参数各自的特点及选用机理,阐明了三者之间异同点存在的原因及合理性,指出了岩土参数选用需要改进的方向,为岩土设计在不同标准要求下,提供了岩土参数选用的参考依据。

The selection of geotechnical parameters has not only commonness but discrepancy among Chinese, European and American geotechnical investigation systems.The selection methods of geotechnical parameters under different systems are analyzed in order to summarize the characteristics and selection mechanism of geotechnical parameters as specified in Chinese,European and American standards,expound the rationality and the cause for the commonness and discrepancy among the above three systems,point out the trend of geotechnical parameters selection.The research results will provide a reference for the selection of geotechnical parameters in the design subject to different standards.
