弹性多层地基刚性路面板的力学分析

Mechanical Analysis of Rigid Pavement on Mnltiple Layered Elastic Foundation

  • 摘要: 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。

     

    Abstract: For the requirement of engineering practice, a new method for analyzing rigid pavement on the multiple layered foundation is presented in this paper. Based on the elastic thin plate theory and the theory of multiple layered elastic system, as well as the Hankel integral transformation, the formulas for calculating stresses, strains and displacements in the plate and the layered foundation under an axisymm-etrical circular uniform vertical load are developed in this paper. This method has been programmed for DPS-8 computer in the computing center, Nanjing Institute of Technology. The method presented in this paper can be used to design rigid pavement with n layered foundation in highway and airport engineering, as well as to analyze the operating conditions of the foundation under the rigid pavement, and hence to investigate the design method of the layered fonudation under the rigid pavement.
