基于G206瑞金城区至济广高速瑞金南出口段公路下穿赣瑞龙铁路绵江特大桥工程,采用midas GTS NX软件建立桩板结构及两侧桥墩模型,进行施工阶段25号及26号桥墩的墩顶位移分析;采用ABAQUS软件建立高铁桥梁上的无砟轨道模型,评估新建桩板结构下穿方案对桥墩及桥上轨道结构的影响.结果表明:桩板结构下穿高速铁路桥梁方案满足高速铁路运营安全要求.
Analysis on Influence of Newly Built Highway Pile-board Structure Underpassing High-speed Railway Bridge
Based on the highway project in the section from G206 Ruijin urban area to Jinan-Guangzhou Expressway Ruijin south exit underpassing Ganzhou—Rujin—Longyan Railway Mianjiang bridge,the model of pile-board structure and piers on both sides is established by using the Midas GTS NX software for the displacement analysis of pier top for#25 and #26 during the construction stage.The ballastless track model of the high-speed railway bridge is built by ABAQUS software,the influence of the newly built pile-board structure underpassing scheme on the high-speed railway pier and the track structure on the bridge are evaluated.The results show that the impact of the pile-board structure underpassing the high-speed railway bridge on the high-speed railway meets the requirements of operation safety.
