无砟轨道桥上交叉渡线受力及变形规律分析

Analysis on the Force and Displacement Rules of the Turnout Scissors Crossing on Ballastless Bridge

基于有限单元法的桥上无缝道岔设计计算理论,分析采用凸型挡台基础连接形式桥上无缝道岔交叉渡线钢轨、传力部件、轨道板和桥梁的受力与变形,归纳出桥上无缝道岔交叉渡线受力和变形规律,并对今后无砟轨道桥上无缝道岔交叉渡线设计提出建议。

Based on finite element method, the design and calculation theory of seamless turnout on bridge analyses the force and displacements of the rail, the pass - force components, the track slab and bridge of the seamless turnout scissors crossing on ballasfless bridge with the cam basement. The forces and deformation rules of the seamless turnout scissors crossing on ballastless bridge are concluded and proposals for its designing in future are made.
