基于灰色关联与逐步回归的黄石市区岩土参数相关性研究
Correlation study of rock and soil parameters in Huangshi urban area based on grey correlation and stepwise regression
摘要
Abstract
In order to obtain more accurate and reliable geotechnical parameters and improve the efficiency of geotechnical investigation,This paper takes the Quaternary Holocene lacustrine(Q4l)silty soil and Quaternary Upper Pleistocene eluvial(Q3el)silty soil in Huangshi City as the research objects,adopts the gray correlation analysis method to analyze the degree of association between various geotechnical parameters,establishes a stepwise regression model,and obtains empirical formulas for mechanical parameters.The results show that the mechanical parameters of the soil are related to its physical parameters,and the correlation between the mechanical parameters and the physical parameters of the two typical soils in Huangshi City is determined.The empirical formula between the mechanical parameters and the physical parameters obtained by the stepwise regression model has a good fitting effect.The research conclusions provide a reference for the rapid acquisition and calibration of relevant parameters of geotechnical engineering investigation.关键词
