摘要
借助有限元数值分析方法,分析环境温度下钢桥面铺装防水粘结层的弹性模量和厚度变化对铺装体系受力的影响。结果表明粘结层的厚度对钢桥面铺装结构的受力影响不显著,粘结层的弹性模量对钢桥面铺装结构的受力影响较大,对于防水粘结层材料的设计和施工具有指导意义。
By means of the finite element numerical analysis, the effects of the elastic modulus and thickness of the waterproof bonding layer on the stresses of the steel bridge deck pavement system under the ambient tempera- ture were investigated. Results show that the thickness of the waterproof bonding layer has not a significant effect on the stresses of the steel bridge deck pavement structures, while the elastic modulus of the waterproof bonding layer has a large effect on the stresses of the steel bridge deck pavement structures, which provide a guiding sig- nificance for the design and construction of the waterproof bonding material.
