    Abstract
  • The authors aimed to use the existed laboratory test data to establish a set of rapid and accurate new method for predicting and evaluating the loess collapsibility. On the basis of the results from laboratory test conducted in Xianyang Loess Plateau, the factor analysis theory,the partial least squares method and the regression analysis method was used. This paper analyzed the correlation between soil physical property index and loess collapsibility coefficient with loess collapsibility mechanism,thus constructing a prediction model of loess collapsibility based on PLS method and LogisticCum function.
