摘　　要：采用数值模拟的方法,分析了桥梁承台基坑在施工过程中对紧邻既有铁路路基稳定性的影响,指出铁路路基沉降主要集中在铁路路基下方及靠近开挖面一侧,靠近基坑中部的路基沉降量要大于一侧的沉降量,并提出紧邻铁路基坑的路基防治措施。其结论可为类似工程提供借鉴与参考。The numerical simulation method was adopted to analyze the bridge pile pit impact on the stability of adjacent railway roadbed during the excavation in this paper. The settlement of railway roadbed was foeused on the bottom and close to the side of the excavation face and the settlement amount close to the middle of the pit is greater than the side of the pit, the prevention measures of roadbed sedimentation close to the railway embankment pit was proposed. The conclusion can provide references for similar projects.
