弹性地基梁是工程中广泛应用的一种结构。对于弹性地基梁的压屈问题,已引起工程力学界的重视。卡曼研究了无限长弹性地基梁的压屈问题,给出计算引起翘曲的最小轴向载荷造成的波长和临界载荷的公式。库马尔(AShwini Kuman)研究了有限长弹性地基梁的压屈问题,给出在该情况下的临界侧向载荷的计算公式。徐元锡利用福里哀级数理论研究了弹性地基梁的压屈问题,并结合我国援建的毛里塔尼亚友谊港的予应力构件张拉台座实例,进行了讨论。
Beams on elastic foundations are a widely used structure in engineering. The buckling and flexion of the elastic foundation beam has attracted the attention of the engineering mechanics community. Kaman studied the buckling problem of an infinitely long elastic foundation beam, and gave the formula for calculating the wavelength and the critical load caused by the minimum axial load causing warping. AShwini Kuman studied the buckling problem of a beam with a finite length of elastic foundation and gave a formula for calculating the critical lateral load in this case. Xu Yuanxi studied the buckling and flexion problems of beams on elastic foundations using the Friuli series theory, and discussed the example of the prestressing member tensile pedestal at Mauritania Friendship Port, which was built in China.
