物元可拓模型的改进及其在膨胀土分类中的应用

Improvement of matter-element extension model and its application to classification of expansive soils

指出物元可拓模型的关联函数是一个分段函数,不便于计算,指标间的互不相容性没有得到彻底解决,影响了物元分析法的应用范围。通过构造一种新的关联函数,改进了物元可拓模型,较好地解决了指标间的互不相容性问题,又便于计算,拓宽了物元分析法的应用范围。将改进的物元可拓模型应用于膨胀土的胀缩等级分类,其合理性和有效性得到了验证。

The paper points out that incidence function of matter-element extension model is not convenient to calculate,and mutual exclusion of indexes has not been solved;so it has an influence on applied range of matter element analysis method.By constructing a new interval incidence function,matter-element extension model has been improved.,and solved mutual exclusion of indexes.The method is convenient to calculate,and widen applied range of matter element analysis method.It has been applied to determine expansive scale of expansive soils;and its reasonableness and effectiveness have been proved.
