【摘要】：为了研究多种因素与长大上坡沥青路面面层内部剪应力的关系,以我国高速公路最常见的二轴车和四轴车为例,通过分析沥青路面剪切流动变形及影响因素,建立了一种移动荷载下长大上坡沥青路面的动力学响应模型.基于正交试验方法对多变量进行了交叉组合计算,通过对计算结果的分析,建立了包括载重、速度、坡度和温度等主要影响因素的长大上坡沥青路面最大横向剪应力综合计算模型.根据长大上坡路段的受力特点,建议在长大上坡沥青路面的设计和施工中增加面内最大剪应力和路面材料抗剪强度控制指标,并给出了多因素综合影响下的长大上坡沥青路面车辙预测模型.
[Abstract]:In order to study the relationship between various factors and the internal shear stress of asphalt pavement surface, taking the most common two-axle and four-axle vehicles as examples, the shearing flow deformation and influencing factors of asphalt pavement are analyzed. A dynamic response model of long uphill asphalt pavement under moving load is established. Based on the orthogonal test method, the multivariable cross combination calculation is carried out. Through the analysis of the calculation results, the load and velocity are established. The comprehensive calculation model of the maximum transverse shear stress of the asphalt pavement on the long slope with the main influencing factors such as slope and temperature. According to the stress characteristics of long uphill section, it is suggested that the maximum in-plane shear stress and the control index of pavement material shear strength should be increased in the design and construction of long slope asphalt pavement. The rutting prediction model of long-rise uphill asphalt pavement is given under the influence of multiple factors.
