Abstract: In the current highway arch bridge design in our country, the calculation of elastic compressive internal force is not considered for the arch axis inclining the dead load compression line. In this paper, the author puts forward a new point of view, and simultaneously points out the mistakes in reference [1].

Key words: arch axis, dead load compression line, elastic compressive internal force

摘要: 我国现行公路拱桥设计及许多高等学校教材中,一般均没有考虑拱轴线与恒载压力线偏离所产生的弹性压缩内力,本文通过理论分析及数值算例,对于大跨径空腹式悬链线无铰拱的恒载内力计算提出了笔者的意见,即有必要考虑这部分弹性压缩内力,以便更准确地反映拱圈的实际受力状态。同时指出了文献[1]中的不足之处。
