摘　　要：太原地铁二号线通达街站在十字路口处采用局部盖挖顺作法施工,其临时路桥体系采用军用梁,且军用梁纵向与行车方向平行。结合工程实例,针对军用梁纵向与行车方向平行时的结构计算方法进行研究,并通过数值模拟进行整体分析,获得了可靠的结论,为后续工程应用提供参考。The crossroads of Tongda Street Station in Taiyuan Subway Line 2 adopts local cover excavation consequent con- struction, the temporary road and bridge system used military beam, and the military beam was parallel to the driving direc- tion vertically. Combined with the engineering examples, this paper studied the structure calculation method in the light of the military beam was parallel to the driving direction vertically, and took a holistic approach by numerical simulation to ob- tain a reliable conclusion, it could provide a reference for further engineering application.
