摘要
本文提出了弹性地基上板的三维应力分析方法。考虑上下板之间既非完全连续，又非完全光滑的接触状态．引用了三维Ｇｏｏｄｍａｎ模型单元。据此编制了旧道面板上加铺层的三维有限元分析程序。经与其它成果对比，证明所编程序正确可靠。
This paper presents the three dimensional stress analysis method of slabs on elastic foundation. Because the interface between the deteriorated pavement and the overlay is completely neither continuous nor smooth, the three dimensional sandwich element of Goodman model is adopted. According to this theory,a triaxial finite element program is devoleped.and is proved to be correct and trustworthy constrasting with other results.
