通过对贵州多年的实际勘察资料，结合多元统计分析，获得了红粘土物理力学指标的一些分布规律，并对比静载试验结果，建立了自检验逐步回归方程，该方程能确切的反映实际中红粘土的力学性质，为进一步地研究红粘土各指标的内在联系打下了基础． Through many years of actual survey data in Guizhou, combined with multivariate statistical analysis, some distribution laws of the physical and mechanical indexes of red clay have been obtained. Compared with the static load test results, a self-test stepwise regression equation has been established, which can accurately reflect the actual red The mechanical properties of clay lay the foundation for the further study of the intrinsic links between the various indexes of red clay.
