摘要
本文基于功能原理,讨论了变截面桥墩的弹性稳定性.用瑞利-里兹法分析并导出了考虑自重的变截面桥墩的稳定计算公式.该方法概念明确、简便易行.
Based on the principle of energy,the paper discusses the elastic stability of high pier with non-uniform section.Using Ray leigh-Ritz method,stability analysis about the high bridge piers with non-uniform section is done and the stability calculation formulas are derived.The calculation formula is clear in concept,simple in computation.
