| 摘 要： | 从悬索结构与具有合理拱轴线的拱结构受力相似的角度出发，将悬索结构在荷栽作用下的线形沿水平面镜像后作为拱结构的压力线．以5次多项式拟合该压力线．从而确定出受力合理的拱轴线。

Discussion on Determination Method of Reasonable Arch Axis |
| |
| Abstract: | Abstract From the view of similar tolerance between suspension structure and arch structure with reasonable arch axis, the linear which forms by suspension structure under the effect of load shall be regarded as pressure line of arch structure after horizontal mirror image. Calculate the pressure line by 5 order polynomials to make sure the arch axis with reasonable tolerance. |
