Put forward the bending stiffness fitting equation with its specific section type, section size, span calculations, and the location of the external load, according which proposed the real bridge stiffness calculation method based on small and medium span prestressed girder bridge standard drawings. 3. 给出预应力梁实际抗弯刚度与其截面形式、截面尺寸、计算跨径及外荷载位置等因素的拟合方程,据此提出针对中小跨径预应力梁桥的刚度推算方法。
Using the theory of coupled vibration between bridge and vehicle, this paper makes an initial study on the lateral rigidity of piers of a medium small span simply supported girder bridge. 应用车桥耦合振动理论,对高速铁路桥墩的横向刚度进行了初步研究。
