| 摘 要： | 借助控制微分方程的标准基本解答组,获得梁弯曲问题初参数形式的通解.在此基础上,给出了弹性地基上不同支承压杆的通解,然后根据实际压杆两端的具体边界条件可简化它们的特征方程,进而求出其临界压力.讨论了由本方法退化到普通压杆时的稳定性问题,与文献中的结果一致.本方法由于具有统一性,也就更有理论意义和应用价值.

| Abstract: | Using the normal solutions of the governing differential equation,the general solution of a bending beam is obtained.Then the general method for compressed bars on elastic foundations is proposed to get the critical pressures.Some simplified bacic cases are discussed,which fits well with the references.As a common way,it is worth with theoretical and engineering values. |
