本文根据工程实践的需要,提出了多层弹性地基刚性路面板的力学分析方法。该方法以弹性薄板理论与弹性层状体系理论为基础,通过汉克尔积分变换,推导了由于轴对称圆形均布垂直荷载所引起的板内应力以及层状地基内各个层次的应力与位移计算公式。该方法已编制成计算机程序,在南京工学院计算中心的DPS—8计算机上应用。得到了满意的结果。本文提出的方法,可以直接用于多层地基的刚性路面或机场道面的设计,也可用于分析刚性路面下基层的工作状态,从而研究刚性路面下基层的计算方法。
According to the needs of engineering practice, this paper proposes a mechanical analysis method for multi-layer rigid foundation rigid pavement. This method is based on elastic thin plate theory and elastic layered system theory. Through the Hankel integral transformation, the plate internal stresses caused by axially symmetrical circular uniform vertical loads and the stresses and displacements at various levels in the layered foundation are deduced. Calculation formula. This method has been compiled into a computer program and applied on the DPS-8 computer in the Nanjing Institute of Technology Computing Center. Satisfactory results. The method proposed in this paper can be applied directly to the design of rigid pavements or airport pavements on multi-layered foundations. It can also be used to analyze the working status of rigid subgrades and to study the calculation methods for rigid subgrades.
