摘要
针对近年来高速公路桥梁搭板普遍出现脱空现象,应用有限元软件,基于文克尔地基梁理论,模拟桥梁搭板计算,分析桥梁搭板在近台端不同脱空长度下其板内力分布及变形情况,并对高速公路典型桥梁搭板配筋情况进行强度验算,为该类病害处理提供借鉴经验。
Aiming at the phenomenon of expressway bridge plate void in recent years,force distribution and transformation inside the bridge plate（near to abutment） at different void length are analyzed and strength check calculation is conducted to reinforcing bars condition of typical expressway bridge plate to provide reference to this damage treatment by using finite element software based on theory of Winkler foundation beam and simulating calculation of bridge plate.
