摘　　要：钢纤维混凝土路面因其良好的路用性能,近年来在重载道路中得到了广泛的应用。而对钢纤维混凝土路面设计普遍存在设计过于保守,板厚偏厚导致造价过高,严重限制了钢纤维混凝土路面的发展,计算分析了钢纤维混凝土路面合理的结构,并对其疲劳寿命和经济性进行了分析,结果表明,重载道路钢纤维混凝土路面最佳厚度为26 cm,疲劳寿命较普通混凝土提高了近百倍,但造价约比普通混凝土提高50%左右。Steel fiber reinforced concrete(SFRC)pavement has been widely used in heavy load roads in recent years due to its good pavement performance.However,the design of SFRC pavement is so conservative and thick that the cost is prohibitively expensive,which seriously restrict the development of SFRC pavement.In this paper,the reasonable structure,fatigue life and economy of SFRC pavement was calculated and analyzed.The results show that the optimal thickness of SFRC pavement for heavy load roads is 26 cm,and the fatigue life is nearly 100 times higher than that of ordinary concrete,but the cost is about 50%higher than that of ordinary concrete.
