基于贝叶斯判别分析方法的膨胀土胀缩等级分类

Classification of the Grade of Shrink and Expansion for the Expansive Soils Based on Bayes Discriminant Analysis Method

应用贝叶斯判别分析理论和方法,选用粘粒含量、粉粒含量、液限、塑限和塑性指数5项指标作为判别因子,建立了膨胀土胀缩等级分类的贝叶斯判别模型。通过具体的计算实例说明了该方法的应用步骤,并对该方法的合理性和有效性进行了验证。

Based on the Bayes discriminant analysis theory and method, and considered five indexes reflecting the shrink and expansion of expansive soil： content of clay grain, content of powder grain, liquid limit, solid limit and plasticity index, a Bayes classification model of expansive soil was established in this paper. An example was given to show the procedure of the model, and the reasonablencess and effectiveness of the model were proved by the example.
