The stiff skeleton is a steel truss structure, which turns into a single cell and single box section of the main arch structure by filling and outsourcing concrete after swivel construction.

劲性骨架为钢管桁架结构，转体施工，之后，通过内填和外包混凝土构成单箱单室箱形截面的主拱结构。

According to the computing result, in the project, the construction risk of continuous steel truss is the largest, followed by box-girder slide shuttering forms and deepwater foundation.

从计算结果来看，在该项目中，连续钢桁梁施工风险最大，箱梁移动模架施工风险次之，深水基础施工风险最小。
