地层渗透性分区和分层方法初步研究

Study of strata permeability classification and optimum partition methods

用聚类分析方法和有序样品最优分割方法对实测地质剖面中不同岩层渗透性进行聚类和分割,有助于解决对勘探资料进行地层分区和分层的问题。该方法对数据整理和分类计算可部分程序化,分类结果更为合理,对以往岩性分层主要依靠经验且任意性较大的情况有一定改善。应用实际资料进行分析,证明了方法的可靠性。

Cluster analysis and optimum partition methods are used for the classification of the stratum permeability based on the drilling data. The proposed methods of classification can be partially programmed for the data processing, which should be helpful to reduce the arbitrary errors of experience method used previously in the classification of soil strata. A river embankment example with 85 cross sections of drilling data was analyzed to show how to use the suggested steps to classify the soil strata. It verified the reliability of this method.
