摘要
为了研究移动荷载作用下水泥混凝土路面沥青加铺层裂缝中点的应力状态,应用abaqus软件分析加铺层厚度、加铺层模量、水泥板厚度、基础模量对沥青加铺层路面应力状态的影响。结果表明:基础模量对沥青加铺层裂缝中点应力影响最大,加铺层厚度和加铺层模量影响次之,但水泥板厚度对裂缝中点应力几乎没有影响。
In this paper, the abaqus software is used to analyze the stress state of the midpoint of the cracks in the asphalt overlay of the cement concrete pavement under the moving load, and the most un-favorable load position is obtained. The effects of overlay thickness, overlay modulus, cement board thickness and base modulus on the stress state of pavement pavement were studied. The influence factors of pavement overlay structure were analyzed. The results showed that the basic modulus Asphalt overlay cracks at the midpoint of the maximum stress, followed by the thickness of the overlay and overlay modulus, the thickness of the cement board basically did not affect.
