摘　　要：采用换算刚度法,对一座9跨不等刚度墩半圆弧无铰拱内力进行计算分析,并基于结构等效换算刚度与内力影响线,得出不等跨连拱内力特点,以期为类似结构分析提供参考。In order to analyze the internal force characteristics of continuous arch bridge, a 9 spans semicircle non hinged arch bridge with une-qual stiffness piers was analyzed by equivalent stiffness method combined with the engineering practice. Based on the equivalent stiffness and in-ternal force influence line of the structure, the internal force of unequal span arch is obtained, which is provided reference for similar structure.

关 键 词：连拱内力 换算刚度法 无铰拱 内力影响线
