介绍石太客运专线黑水坪特大桥(48+3×80+48)m刚构-连续组合梁桥的概况,结合客运专线对桥梁设计纵、横向刚度的要求,针对高墩、大跨刚构-连续组合梁的刚构桥墩在横向刚度、纵向刚度以及墩底弹性约束等方面进行研究比较,对于高墩、大跨刚构-连续组合梁在客运专线上的应用以及刚构墩的结构形式提出看法。
This paper introduces the general situation of the rigid-continuous composite beam bridge of Shihhot-Passenger Dedicated Line (48 + 3 × 80 + 48) m. Combining with the requirement of longitudinal and transverse stiffness of the bridge designed by Passenger Dedicated Railway, The research and application of rigid-framed pier of composite-continuous composite beam in terms of transverse stiffness, longitudinal stiffness and elastic constraint at the pier bottom. The application of high pier and long-span rigid-frame composite continuous girder in passenger dedicated line and the structure of rigid framed pier Form to put forward the view.
