摘要
选取了一个满足边界条件的新的挠度函数,利用迦辽金法解答了无拉力Winkler地基上梁的脱离问题.所采用的方法具有计算简单,收敛速度快的特点.计算结果表明:Winkler地基上梁弯曲时不考虑脱离时的解答与无拉力Winkler地基的解答有明显的差异,且当荷载位置保持不变,按比例增大时,梁与地基的脱离区并不发生变化.
In this paper, the bending problems of beams on tensionless Winkler foundation are investigated with Galerkin method. The distinctiojn of the used methods are simple in computation method and fast in convergence . The numerical results show that there are obvious differences between the solutions of beam on Winkler foundation and tensionless Winkler foundation.
