摘　　要：针对建设空间狭小,同一地点多条铁路、公路交叉等原因形成的平面位置和高差等空间受限因素,开展东莞市城市快速轨道交通R2线交叉设计研究。在保持地面汽车交通正常通行、施工不影响地下城际铁路隧道的前提下,采用单双层门式框架墩、连续梁、U形梁等特殊结构,解决受限空间内复杂立体交叉的设计难题。该研究可为类似项目设计提供参考。In view of the spatial constraints such as plane position and elevation difference caused by narrow construction space and crossing of multiple railways and highways,the study is carried out on the crossing design of Dongguan Urban Rapid Rail Transit Line R2.To maintain normal automobile traffic on the ground and ensure the underground intercity railway tunnel is not affected by construction,special structures such as single and double-layer portal frame piers,continuous beams supported by concealed beams and U-beams are adopted to solve the design problems in case of complex grade separate in confined space.This study may be used as reference for similar design.
