模糊数学在某段公路膨胀土分类判别中的应用

Application of Fuzzy Mathematical Model to Classification of Expansive Soils for a Section of Highway

对膨胀土的判别与分类方法较多,但都存在着一定的缺陷,对工程实践存在着不良的影响.模糊数学模型自建立以来,在自然科学的很多领域中得到了广泛的应用并取得了显著的成效.在宜黄公路施工中运用模糊数学模型对膨胀土进行分类判别,成功地解决了江宜段膨胀土处理和利用问题,使该段土工工程能正常施工和使用,取得了较为理想的效果.

There are several methods of the identification and classification of the expansive soil;but all have some shortcomings,which have adverse impact on the practice of project.In light of this situation,during the construction of Yi-Huang Highway,the author adopted fuzzy mathematical model to classify and discriminate the expansive soil.The method is a new application,which has successfully resolved the treatment and use problem of the expensive soil of Jiang-yi section,so that the geotechnical engineering has already practiced and used normally.
