摘　　要：本文用空间桁架位移法计算桅杆的整体稳定。计算中考虑了结构在大位移情况下的几何非线性,从而得到了较为精确的解。将精确解的结果与习用的铰链法和平均参数法加以比较,得出了对实际设计工作有益的结论。Considering the guyed-mast as a space truss and taking into account the geometrical non-linearity of the structure due to large displacements, the overall stability of the structure is analyzed and computed precisely. The results are compared with those obtained by the conventional hinge-joint method and the average parameter method, obtaining conclusions which are useful in designing practice.
