摘要:
为分析贫混凝土基层沥青路面新型路面结构的基层应力情况,通过有限元分析方法计算贫混凝土基层的荷载应力,并利用弹性层状体系理论分析沥青面层厚度对其影响,由此推导出基层荷载应力的计算公式.根据不同自然区划的温度场和最大温度梯度,得出贫混凝土基层沥青路面中的基层温度应力的有限元解,于此提出了基层温度应力的计算公式.上述两公式为贫混凝土基层沥青路面结构中基层厚度设计的重要依据.
Abstract:
In order to analyze the base stress of the new pavement structure of asphalt pavement of poor concrete base layer, the load stress of poor concrete base layer is calculated by finite element analysis method, and the influence of asphalt surface thickness on it is analyzed by elastic layer theory, and the calculation formula of base load stress is derived. According to the temperature field and maximum temperature gradient of different natural divisions, the finite element solution of the temperature stress of the base layer in the asphalt pavement of the poor concrete base layer is obtained, and the calculation formula of the base temperature stress is proposed. The above two formulas are important bases for the design of base layer thickness in asphalt pavement structure of poor concrete base layer.
