摘要
文章介绍了高韧性水泥基材料的定义,基本力学特性及在桥梁结构中的应用现状。在基本力学特性方面阐述了高韧性水泥基材料的受压、受拉、弯曲、抗剪特性及自修复性能;在桥梁结构中的应用现状方面,从ECC桥面修补或加固、钢/ECC组合桥面板、ECC韧性连接板及FRP网格与ECC的组合应用等几个方面做了简单介绍。
This paper introduces the definition of engineered cementitious composites material and its basic mechani- cal properties and the present situation of application in bridge structure. In the aspect of basic mechanical properties, the paper expounds the compression, tensile, bending and shear properties and self-healing capability of ECC. In the as- pect of the application situation of bridge structure, this paper gives a brief introduction of ECC bridge deck repair or strengthen,steel/ECC composite deck,ECC ductile connection plate and the combinatorial application of FRP grid and ECC.
