摘　　要：本文对天府机场高铁站下穿天府国际机场航站楼咽喉区区间隧道转换顶板结构方案进行必选,采用MIDAS/GEN建立实体单元受力分析,比对两种转换形式上受力的优缺点,提出圆拱厚板转换设计的设计建议,为其它隧道结构下穿建构筑物转换工程设计提供参考。This paper selects the scheme of the transition roof structure of the sectional tunnel of Tianfu Airport High-speed Railway Station underpassing the station throat of Tianfu International Airport Terminals,in which MIDAS/GEN is used to establish solid unit stress analysis,to compare the two transition forms for their advantages and disadvantages,and put forward some suggestions on the transition design of circular arch thick plate,which provides a reference for the transition engineering design of other tunnel structures.

关 键 词：隧道 平顶圆拱 转换厚板 实体单元
