With the rapid development of urban rail transit and intercity railways,there are intersections between the two on the line,where proximity,underpassand overpass present construction challenges.The article uses the Heping Station of Shenzhen urban rail transit L12 as the background project,focusing on how to ensure safe construction of intercity railway bridges in close proximity to soft soil layer rail transit stations.It studies the protection scheme of bridge piers,excavation procedures of foundation pits,and other aspects.The construction adopts new technologies such as steel support servo system control.Through construction monitoring results,it has been proven that the deformation of intercity railway bridges and station foundation pits is controllable,the structure is safe,and the safe construction of intercity railway bridges under rail transit stations has been achieved.
