摘要
结合华北地区某大型水泥混凝土桥面沥青铺装层工程,将半结构多目标模糊优选评价理论应用到桥面铺装防水体系方案比选中。根据桥面铺装防水体系需要综合考虑的几个方面,建立综合评价指标体系,通过确定各指标对分系统相对优属度矩阵及分系统对总决策的相对优属度向量,并确定出各方案对总决策的优越度,最终比选出方案1(热SBS改性沥青与0.5%单粒径预拌碎石封层+2 cm沥青胶砂防水层+改性乳化沥青粘层)为最优方案。
Relying on bridge deck pavement for a large concrete bridge in North China,the half-structural and multi-objective fuzzy optimization theory is applied.According to considering several as-pects of waterproof system of bridge deck pavement,comprehensive evaluation index system is estab-lished.Through determining the relative subordinate degree matrix for the criteria and the relative subor-dinate degree vector of the sub-system to total decision,the preponderance of the scenarios chosen to the total decision are decided,and finally program 1 that is seal coat of heat SBS modified asphalt and 0.5%single particle size premixed gravel +waterproof layer of 2 cm asphalt sand +sticky layer of modified e-mulsified asphalt is selected as the optimal scheme.
