Discussion on Optimal Parameters Combination of Arching System Based on Composite Main Arch Circle Method

基于复合主拱圈加固拱桥技术中锚固系统最佳参数组合探讨

After construction of the main arch, and reaching the designed strength, sandbags made of canvas were used to unload.

主拱圈施工完毕，达到设计强度后，设计制作了丁纶帆布砂袋进行卸载落架。

A steel and membrane structure is planed to build in South China Agricultural University. The span of the main arch is 103m and the span of the minor arch is 21m.

华南农业大学东区运动场看台是由跨度为103m的大型钢桁架主拱、21m钢桁架次拱以及膜结构组成的钢-膜组合结构屋盖。

洋山深水港南北闸桥工程主拱施工技术

Because the main arch and the center line of the bridge in the horizontal projection is misaligned, the deformation and stress distribution of the bridge are very complex.

主拱肋轴线水平面内的投影与桥梁中心线的不重合，全桥的变形和受力情况都很复杂。
