对于钢桁梁，用国外的"桥面吊机杆件拼装法"，由于工艺和设备水平所限其工期长，远不能满足中国桥梁建设工期的要求，在分析山区大跨悬索桥主梁架设困难的前提下，经过多方案比选提出矮寨大桥"自行式跨缆吊机荡移"架设主桁方案，这是山区悬索桥主梁架设的又一个重大的创新。

The ratio of the vertical load distributed between the arch rib and the tie beam of the two schemes is the same. For the integral girder deck scheme, the longitudinal beams and the deck slab of endure more axial force compared to the ballast girder deck scheme, especially to the deck slab with a conspicuous increase of the axial force and higher stress, and the tie beam endure less. The force-bearing characteristics of the cross beams under the integral girder deck scheme is obviously better than that of the ballast girder deck scheme, especially at the two ends of each cross beam.

在受力上，与道碴板桥面方案相比，整体桥面方案竖向荷载在拱肋和系梁之间的分配基本相同，混凝土板和纵梁分担的纵向力则相对更大，尤其是混凝土板，增幅较明显，应力水平整体较高，系梁分担的纵向力则得到减小，横梁的受力状况整体桥面方案明显优于道碴板桥面方案，特别是在梁端处。
