摘要:
将模糊集与粗糙集理论引入混凝土结构耐久性环境区划中,在实测数据离散化的基础上对原始数据进行挖掘,将各种耐久性影响因素的权重分配问题转化为粗糙集的属性重要性评价问题,得出混凝土结构耐久性影响因素的关系数据模型,经过属性值特征化建立了知识系统,通过分析各影响因素对混凝土结构耐久性的影响程度,提出了混凝土结构耐久性环境区划方法.对深圳地区混凝土结构耐久性环境区划结果表明,该方法有效地克服了传统定权方法的缺点,使评价结果更具客观性,提高了综合评判的准确性和有效性.
Abstract:
In this paper, fuzzy set and rough set theory were used in the research of durability environmental division of concrete structures. Based on discretization of the measured data, the significance of attributes among rough sets was estimated instead of weight determination, and a relational data model about the durability effecting factors of concrete structures was established. A knowledge system was built through making attribute value into eigenvalue. After that, the method of durability environmental division is established by analyzing the degree of influence which various factors have on the durability of concrete structures. The researching on durability environmental divisions of concrete structures in Shenzhen City shows that the proposed approach overcomes the subjectivity of traditional weight determination method. It possesses much more objectivity and has improved the accuracy and efficiency of comprehensive evaluation
