在研究中发现简支梁模型所存在的问题，值得注意。
The problem of beam model, which is found during the research, deserve our attention.
本文以均匀粘弹性简支梁作为梁形柔性基础的力学模型。
The viscoelastic simple beam is taken as the mechanical model of flexible foundation with beam-wise.
因此，桥梁上部采用先简支后连续梁结构越来越多。
Therefore, the upper bridge with simply supported continuous beam structure more and more.
