| 摘 要： | 利用Ｈａｍｉｌｔｏｎ原理导出了复合材料叠层梁稳定性问题的控制方程和边界条件，并由此进一步导出了Ｗｉｎｋｌｅｒ－Ｐａｓｔｅｒｎａｋ地基上叠层梁稳定性问题的控制方程，其次，在不同的边界条件下，利用此控制方程获得了相应的屈曲载荷方程，并进行了具体的数值计算，同时讨论和分析了地基参数对屈曲载荷的影响，得到了一些很有价值的结论。

| Abstract: | The governing equations and boundary conditions of stability of composite laminated beams are obtained by using Hamilton's principle t Furthermore, the governing equations of stability of the beams on Winkler-Pasternak foundations are inferred on the basis of the former. The corresponding equations of buckling loads qre obtained by using them under different boundary conditions and are applied for calculation of the critical loads of the beams. In addition,by analysis and discussion of the effects of the foundation parameters on buckling loads, some valuable conclusions are drawn in the paper. |
