摘　　要：随着我国现代交通运输事业的不断发展,桥梁工程作为交通网络的咽喉具有十分重要的意义。针对目前桥梁建设中普通混凝土难以满足性能要求、超高性能混凝土能耗过高的现状,研究生态型超高性能混凝土在简支梁桥中的应用,采用修正的安德森模型进行基体配合比设计,然后建立有限元计算模型,最后结合生命周期技术进行桥梁成本分析和环境评价。结果表明回收铅锌尾矿可制得生态型超高性能混凝土,有效降低了超高性能混凝土的能耗与成本,同时将其应用于简支桥梁时,在其生命周期内具有较大的经济性和环保性,符合可持续发展战略,在未来的桥梁建设中具有深远意义。With the continuous development of modern transportation in China,bridge engineering,as the throat of traffic network,has a very important strategic position.In view of the fact that ordinary concrete is difficult to meet the performance requirements and the energy consumption of ultra-high performance concrete is too high in bridge construction at present,the application of graduate ultra-high performance concrete in simply supported beam bridge is discussed.The modified Anderson-Andresen model is used for matrix mix design,and then the finite element calculation model is established.Finally,the bridge cost analysis and environmental evaluation are carried out with life cycle technology.The results show that the ecotypic ultra-high performance concrete can be prepared by recovering lead-zinc tailings,and the super-high performance concrete can be effectively reduced.The energy consumption and cost of energy concrete,when applied to simply supported bridges at the same time,has great economy and environmental protection in its life cycle,conforms to the sustainable development strategy,and has far-reaching significance in the future bridge construction.
