| 摘 要： | 传统上，对于依据原始资料进行地层的划分与合并往往依靠工程师个人的经验与习惯。引入了模糊聚类概念，提出了一种根据基本物理力学指标进行土层归并分类的合理方法，物理意义明确，计算简捷，具有普遍意义。还提出了一种用参数的变异系数来检验模糊聚类结果的方法，使模糊聚类的结果与统计参数对应起来，从而使验证结果满足规范的规定，保证了地层归并的合理性。

| Abstract: | Traditionally, it is usually depended on engineers’ personal experience and habits to establish the strata layers on the basis of the original data when they doing the desk studies of a site investigation work. The concept of fuzzy cluster is introduced to propose a more reasonable way to merge and classify the soil based on the physico-mechanical indexes of the soil. It can be seen that this method is more simple and universal. In addition, a method used to check the results of fuzzy cluster based on the variation coefficients study of the soil parameters is proposed. The results of fuzzy cluster are corresponding with the statistical parameters; meanwhile, the method also can be used to guarantee the results to meet the standard requirements; and the rationality of the way about merging of soil is proved subsequently. |
