地铁隧道下穿既有铁路施工对铁路路基稳定性影响分析

Analysis of Influence of the Construction of Subway Tunnel Passing Through Existing Railway on Stability of Railway Subgrade

在地铁隧道下穿既有铁路施工过程中,铁路路基稳定性可能会因为土体扰动而受到干扰,从而出现路基沉降、变形等问题,不利于铁路运行安全稳定。尤其是在城市区域铁路施工方面,可能会影响到居民日常生活与工作。论文对地铁隧道下穿既有铁路施工在铁路路基稳定性方面产生的影响和铁路路基稳定对策进行了研究。

During the existing railway construction process under the subway tunnel, the stability of the railway subgrade may be disturbed by the soil disturbance, thus the settlement and deformation of the subgrade will appear, which is not conducive to the safety and stability of the railway operation. Especially in urban area railway construction, it may affect the daily life and work of residents. This paper first analyzes the influence of the subway tunnel under pass the existing railway construction on the stability of the railway subgrade, and then studies the countermeasures for the stability of the railway subgrade.
