路基膨胀土判别和分类的属性测度模型

Attribute measurement model for identification and classification of expansive soil in highway subgrade

  • 摘要: 将属性数学理论应用于膨胀土的综合评判中,建立路基膨胀土判别与分类的属性测度模型.首先根据对膨胀土的评判要求,结合高速公路路基膨胀土的判别与分类实践,提出用于膨胀土综合判别的评价指标.然后根据属性数学理论构造单指标属性测度函数,以属性测度函数计算单指标属性测度,以客观性权重对指标进行赋权以计算多指标综合属性测度,以该综合属性测度对膨胀土的膨胀等级进行判别.最后以置信度准则进行膨胀土胀缩等级的属性识别.实例研究表明,该模型的评价结果与评判法、模糊综合评判法的评价结果基本一致.
