The results show that, with the same steel consumption, the longitudinal and transverse girder deck scheme is a little better in stiffness, dynamic characteristics and stability than those of the other scheme's. For the dense transverse girder deck scheme, because of no longitudinal beams, the axial forces of the tie beam and the deck slab are higher than those of the other scheme's. The improving rate of the axial force for the deck slab is about 50%. The inside and outside bending moments of the cross beams reduce to below half of the other scheme's. The longitudinal stress of the deck slab is higher on the whole and the traverse stress is less than that of the other scheme's. The maximum traverse stress of the deck slab is below 40% of the other scheme's.
研究结果表明:在材料用量相同时,纵横梁方案桥梁刚度较密布横梁方案的桥梁刚度稍大,桥梁动力特性比后者的优,其稳定性也比后者的强;对于密布横梁方案,由于不设纵梁,系梁和混凝土板承受的纵向力都较纵横梁方案的大,混凝土板增幅达50%左右,横梁面内和面外弯矩则明显减小,都低于纵横梁方案的一半,混凝土板顺桥向应力整体比纵横梁方案的高,而横桥向应力则较低,最大值低于纵横梁方案的40%。

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。
