既有铁路特小角度立交工程方案研究

Study on small angle interchange engineering of existing railway

通过对下穿工程实例进行方案研究,从工程方案、施工方案两方面进行了综合论述,对高速公路以特小角度下穿既有铁路的设计理念、施工方法提出了新的思路,解决了在不影响既有铁路运营条件下,高速公路以特小角度下穿既有铁路的难题。

Through planning research of engineering under railway example,it was discussed from engineering planning and construction planning comprehensively.The new thinking of design concept and construction method about express highway under existing railway with super small angle were proposed,which resolved express highway under passing existing railway with super small angle without influencing existing railway running.
