摘要
基于对水泥混凝土路面-轮胎相互作用时产生的泵吸作用、振动作用、空气动力特性等噪声形成机理和相关影响因素的分析,指出降低水泥混凝土路面噪声可以从噪声源和传播途径2个方面着手。通过改变路面结构和改进施工工艺等措施,能够将水泥混凝土路面的噪声降低到人们可以接受的程度。
Based on the analysis of the mechanism of pumping, vibrating, dynamical slipstream and relative effecting factors, it is put forward that the noises origin and transmitting passes should be controlled to reduce noises. The noises level can be reduced to acceptable degree by changing pavement configuration and construction technology.
