摘要
分析目前我国公路的轴载特性,并通过三维有限元的计算手段,分析了考虑更接近实际的荷载非均匀分布时,路面结构内的力学响应。通过分析发现,考虑更接近实际轮载对沥青路面的作用,对更深入地了解沥青路面结构的力学行为至关重要。
At present, with the national economy developing rapidly the load characteristics of the vehicles traveling on highway have changed obviously in our country. The tyre contact area distribution can't be described as circle and uniform. In this paper, the current load characteristics of highways in our country are analyzed and a calculation method of the three dimensional finite element is used to analyze the mechanical response within the structure of asphalt pavement when considering more practical non-uniform distribution of load. Through analysis it is found that it is very important to take the influence of the wheel load closer to the practical one into consideration and get deeper understanding of the mechanical characteristics of asphalt pavement structure.
