摘要： 本文介绍了逐步回归方法及其电算程序的功能,并籍此对文献[1]所归纳的有关数据进行了定量分析,以确定其控制内力的L.Q标定函数,从而给出大跨径预应力拱式桥架桥上下弦合理刚度比的解析解。

Abstract: This paper adopts the method of the gradual regression analysis and the ability of the computer's program and as well as induces the quantitative analysis by means of relative data to the reference (1), so that L. Q-qualified function on the controlled internal forces are determined, therefore the analysis solution of the rational stiffness ratios of upper and lower chords on the prestressed concrete cantilever arched-truss bridge is found.
