摘　　要：笔者依据自己的编程实践，提出了计算柱式墩台的电算方法，即全面采用有限元自动建模、动态加载、逐次逼近、循环迭代等方法，可得到较为精确的计算结果。该算法适用于简支梁、简支变连续梁、连续梁，可一次性完成全桥计算，有着广泛的适用性。By own programming practice, the author proposes the computor calculation methods for counting the column pier, namely methods for overall adopting the finite element automatic establishment of model, dynamic loading, successive approximation and cycle iteration, which could get relatively exact results of calculation, are suitable for simply -supported beam, simply -supported to continous beam and continuous one, moreover would one - off complete computation of entire bridge, having wide adaplability.
