On the basis of the generalized phase integral approximation and the beam displacement ray mode theory, which are both developed by Chinese acousticians, a fast method for normal modes analyzing including the leaky modes is presented. The application of this method in the coupled mode parabolic equation theory gives an efficient algorithm for both the range dependent problems (CMPE2D) and the three dimensional problems (CMPE3D).

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.
