Analysis of Mechanical Properties of Simply Supported Hollow Slab Skew Bridge

采用力法和位移法求解简支斜梁的内力影响线,通过影响线获得斜交角度和弯扭刚度比对斜交桥内力的影响;采用正交梁格法对不同斜交角度的简支空心板斜交梁桥进行建模,通过对模型的分析和总结,得到了简支空心板斜交梁桥的力学特点,可为简支空心板斜交梁桥的设计和施工提供参考。

The force method and the displacement method are used to solve the internal force influence line of the simply supported skew beam.The influence of the skew angle and the bending torsion stiffness ratio on the internal force of the skew bridge is obtained by the influence line.The orthogonal beam grid method is used to calculate the simply supported hollow slab skew bridge of different skew angles.Through analysis and summary of the model,the mechanical characteristics of the simply supported hollow slab skew bridge are obtained,which can provide reference for the design and construction of the simply supported hollow slab skew bridge.
