天津港地区土层剖面随机场特征参数的估计
ESTIMATION OF RANDOM FIELD CHARACTERISTIC PARAMETERS OF SOIL LAYERS AT TIANJIN PORT
摘要
Abstract
The environment and conditions for both natural and artificial soilsat different places are similar. Therefore physical and mechanical properties of soil samples are relevant.The relevance can be analyzed with random field theory.To estimate spatial characteristics of physical and mechanical properties of soil in Tianjin Port, tests such as boring in situ and standard cone penetration are employed to acquire enough test data that are essential to the employment of random field theory.Because it can continuously obtain enough data,the standard cone penetration test is the main method to get test data.The data is used to inspect the stationary and ergodicity of this area.Results show that the random field model put up by Vanmarcke can be employed in this research.In this paper,the innovation points include that the method establishing random field model in Tianjin Port is discussed and the characteristic parameters of typical layers in this area are estimated with the improved non-correlation method.The result can lay a solid foundation for reliability analysis in geotechnical engineering in Tianjin Port.This method of estimating characteristic parameters of random field can be used for other areas.关键词
