摘　　要：以下穿华北地区某单线普通铁路浅埋暗挖隧道工程为背景,对此类项目的设计计算方法进行了研究,从初支、二衬的结构验算,管幕变形及其应力检算、地表沉降计算等几个方面进行了分析。This paper has researched the design and calculation method of this kind of project based on a shallow mining excavation tunnel under crossing on signal -line ordinal railway in north China. The analysis has been implemented from the following aspects：structure safety checking of initial support and secondary lining, pipe- curtain deformation and stress checking, ground settlement. Calculation method stated here deserves reference by other similar projects.
