    THE APPLICATION OF STATISTICAL METHODS ON INITIAL SUBSIDENCE PRESSURE OF LOESS

    • Based on the factor analysis, principal component analysis, and linear regression, the statistical analyses were done in 5 index of the loess physical properties which include the density, moisture content, porosity, liquid limit, plastic limit, and the initial subsidence pressure. Analysis shows that the subsidence pressure is moderately related to the density, which is low-alcohol related to the moisture content and porosity, and which is not related to plastic limit; the density is high related to porosity, and the moisture content, porosity and liquid limit had low-alcohol relation; the initial subsidence pressure was caused by multiple factors, the comprehensive statistics of physical and mechanical parameter can be used to determine the initial subsidence pressure.
