一般多孔拱桥,应按连拱内力影响线布置荷载,计算拱中最大活载内力.本文提出任意多孔连拱内力影响线的计算公式和最大活载内力的计算方法.
In general porous arch bridges, the load should be arranged according to the influence line of arch internal force and the maximum internal force of arch should be calculated.This paper puts forward the calculation formula of the influence line of arbitrary internal force of arch with multiple holes and the calculation method of the maximum live load internal force.
