摘要
提出利用已有同类问题的等截面拱型结构的求解结果，来解决变截面拱型结构稳定性分析问题的一种新的数值解法———均值法．均值法不仅计算简单易行。
In this paper the method of weighted mean is applied to the stability analysis of the arch structure with variable cross section .In comparison with the popular finite difference and element method,this method is characterized with high accuracy and great economy in computing time.Practice shows its effctiveness and advantage.It is proved that this method is clear in concept and effective in computation.
