【摘要】 提出"钢板-剪力件-钢筋网-钢纤维轻集料混凝土"的新型钢桥面铺装组合方法。研究钢纤维轻集料混凝土力学性能及其与钢板组合件的静力学特性。结果表明:剪力件、钢筋网和高强高韧性钢纤维混凝土显著提高了钢桥面铺装体系的承载能力,阻止了铺装层的推移和掀起,提高了铺装层和钢桥面板协同一致变形的能力,并成功应用于实际工程。更多还原

【Abstract】 The lower density,higher toughness and insulating are the obvious characteristics of steel fibre reinforcement lightweight aggregate concrete(SFRLWC).Raising a new combined method of"shear connector-steel net-SFRLWC"for the pavement of steel deck bridge.The mechanic properties fo SFRLWC and its static mechanic performance with steel plate were studied.Results show that loading ability of bridge system was remarkably strengthened by using shear connector-steel net-SFR- LWC,which stopped the pavement from moving,and promoted the ability of according deformation. It is successfully applicated in real project.更多还原
