The error of ultimate load prediction of un-reinforced brick arch: brick arch will be simplified to portal frame are used to preliminary estimation, in-plane stiffness which only provides from vertical frame, the average error between -20~20%;Structure program are used to simulate brick arch with shell elements analyzed, the average error between -15%~10%.

未补强砖拱，其水平极限荷载预测之误差：推估公式中将砖拱简化为门形构架，其面内刚由垂直构材提供，平均误差在-20~20%之间；结构分析程式中将砖拱以壳元素模拟，平均误差在-15~10%之间。

Brick arch failure mode:Cracks are separated into shear and flexural cracks, the shear and flexural crack of un-reinforced brick arch occur in arch angle 63o respectively and at the bottom of 3rd brick walls on both sides of opening.

砖拱破坏模式：缝大致上可分为剪缝与挠曲缝；未补强砖拱斜向剪缝发生处为拱心角约63o 处，挠曲水平缝发生於开口侧底部三皮砖位置。

Using the method, studies reveal that the stability of arch dam against buckling is generally governed by the top arch ring and the cantilever is more steady than the horizontal arch.

利用该法研究表明：坝体结构失稳的控制拱圈一般在拱顶，悬臂梁的稳定性高于水平拱圈。

As a compress-bend structure, with increasing of the span, length slender ratio and carrying load of arch increase, lateral rigidity and width span ratio of arch ring minish relatively. During construction and service stages, lateral stability becomes more important and a control factor of arch bridge design.

拱肋作为压弯结构，随着跨径的增大，杆件的长细比及所承受的荷载也随之增大，拱圈横向刚度、宽跨比相对减小，在施工阶段及使用阶段横向稳定问题特别突出，常常成为拱桥设计的控制因素。

As a structure that is compressed and bended, with increasing of the span, length slender ratio and carrying load of arch increase, lateral rigidity and width span ratio of arch ring minish relatively. During constructing and bring to bear, lateral stability becomes especially severity and a control factor of arch bridge design.

拱作为压弯结构，随着跨径的增大，杆件的长细比及所承受的荷载也随之增大，拱圈横向刚度、宽跨比相对减小，在施工阶段及使用阶段横向稳定问题特别突出，常常成为拱桥设计的控制因素。

On the project background of Rongzhou Bridge, a half through CFST arch bridge in Yibin crossing Jinshajiang, the optimizing theory is applied to the calculation of the stayed-buckle-cable forces in the process of craning construction of the steel-tube arch segment and construction error adjusting. The calculated optimum cable forces with high precision can guarantee the inner forces and the structuredeformation in safe state, and ensure the line shape of the arch ring in accordance with design requirements as well.

以宜宾金沙江戎州大桥(主跨260m的中承式钢管混凝土拱桥)为工程背景，将优化理论引入到钢管混凝土拱桥拱肋架设和扣索索力调整计算，这样计算出的索力精度较高，既能确保结构的受力状态和变形始终处在安全范围内，又能保证架设和调整后的拱肋线形符合设计期望。
