摘要
高性能混凝土因其优异的力学特性和耐久性能而具有广阔的应用前景,其中最受瞩目的是超高性能混凝土(UHPC)和应变硬化水泥基复合材料(ECC),将其与钢桥面板的组合是近年来桥梁工程中新材料应用的典型范例。通过对钢-高性能混凝土组合桥面板的静力抗弯性能、疲劳性能、界面抗剪性能和负弯矩区抗裂性能等方面的研究和相关设计规范进行了归纳总结,提出目前高性能混凝土在钢桥面铺装中应用亟待解决的系列问题,为相关领域的研究和工程应用提供参考。
High performance concrete(HPC)has broad prospects for its excellent mechanical properties and durability,and the most representative ones are ultra-high performance concrete(UHPC)and engineered cementitious composites(ECC).The combination of HPC and orthotropic steel bridge deck is a typical example of new material application in bridge engineering in recent years.The research progress about mechanical properties,fatigue properties,shear resistance and crack resistance in negative moment region of orthotropic steel-high performance concrete composite bridge decks are summarized and the specifications and standards of high performance concrete are summarized.Also,the problems and prospects in the emerging stage are put forward.These could provide a reference for the future research work and engineering application in related fields.
