摘要
考虑板的横向剪切变形及板的横向法向应变和弹性地基影响，提出在弹性地基上厚板的二维弹性动力学近似理论．导出了弯曲问题的控制方程，其通解用两个无向函数表示，同时得出控制方程的解析解，并给出数值结果．
Considering crosswise shearing deformation, cross normal strain of plate and plastic foundation influence, a similar theory of Z-D plastic dynamics of thick plate on plastic foundation is put forward. And a control equation of the bending question is also established. Its general solution is showed by two nodirection functions. The analytic solution of the control equation and the result of numerical value are obtained.
