摘　　要：基于时代发展,我国交通事业发展较为迅猛,其隧道工程建设规模和数量日益提升。而在具体隧道施工过程中,部分工程涉及到铁路的下穿。而当隧道下穿过程中,既有铁路势必会受到不同程度的影响,进而引发路基沉降等现象,对铁路实际作用的发挥产生严重的影响。基于此,本文针对新建隧道下穿施工对既有铁路的影响问题进行分析研究。With the development of the times, China's transportation industry is developing rapidly, and the scale and number of tunnel construction projects are increasing. In the concrete tunnel construction process, part of the project involves the underpass of the railway. When the tunnel underpassing railway, the existing railways are bound to be affected to varying degrees, which in turn causes roadbed settlement and other phenomena, which has a serious impact on the actual operation of the railway. Based on this, this paper analyzes and studies the impact of the new tunnel underpass construction on the existing railway.
