摘　　要：依托河北省太行山高速公路京蔚段与沙蔚铁路的相交工程,对湿陷性黄土地质状况下穿越既有铁路的顶推箱涵施工技术要点进行介绍。通过一系列保证措施以及严密的监控量测技术确保施工过程中铁路的正常运行,为今后相似地质状况下顶推箱涵施工提供指导。This paper is based on the intersecting project of the Jing Yu section of the Taihang Mountain Expressway in Hebei province and the Sha Yu railway. It mainly introduces the construction techniques of pushing box culvert in collapsible loess geological conditions through existing railway. A series of guarantee measures and strict monitoring measurement techniques can ensure the normal operation of railway during the construction process. It can provide a reference for the similar geological condition of pushing box culvert in the future.
