钢纤维混凝土路面结构的疲劳特性

Fatigue Properties of Steel Fiber Reinforced Concrate Pavement Structure

通过半刚性基层上对不同钢纤维掺量的足尺混凝土面板疲劳特性和承载能力的测试，建立了基于基准混凝土的累计轴载作用次数和钢纤维掺量等因素的钢纤维混凝土（SFRC）疲劳方程．通过实例计算表明该方程可以预估和指导SFRC的工程应用．

After the fatigue property and load bearing capacity test of full - scale concrete slabs admixed with variable amounts of steel fiber on the semi - rigid type base, the fatigue equation of SFRC was built based on the accumulated axle - load acting number and steel fiber content. The formula can be applied to forecast and guide the engineering practice of SFRC through the calculation example.
