摘要
为了分析不同因素对交叉口路面结构的影响,基于理论模拟方法,通过改变沥青层的模量和结构层层间接触状态,计算不同工况下交叉口路面结构力学响应,分析不同影响因素对路面结构力学特征的影响。结果表明:在一定范围内,增大沥青层模量有利于提高路面结构抵抗荷载破坏的能力,层间连接越强对结构层整体受力越有利,水平荷载和超载则不利于路面结构受力。
In order to analyze the influence of the different factors on the pavement structure of intersections,based on the theoretical simulation method,the mechanical response of the pavement structure of intersection under the different working conditions is calculated and the influence of the different factors on the mechanical characteristics of pavement structure is analyzed by changing the modulus of the asphalt layer and the interlayer contact state of the structural layers.The results show that the increment of the modulus of the asphalt layer within a certain range is beneficial to improve the ability of the pavement structure to resist the load damage.The stronger the interlayer connection is,the more favorable the overall stress of the structural layer is.The horizontal load and the overload are not conducive to the stress of the pavement structure.
