摘　　要：东南沿海地区滨海软土特别发育,临时工程的不当设置,将影响铁路工程路基的稳定。结合福厦铁路玉塘洋特大桥台尾路基垮塌实例,对垮塌原因进行分析,提出了以桥代路方案,实施结果保证了路基工程的稳定性,和福厦铁路施工的顺利推进。The marine soft soil develops works may influence stability of railway well in the southeast coastal areas so that improper setting in temporary subgrade. Combining with the practical case of subgrade collapse in the tail section of Grand Yutangyang Bridge on Fuzhou-Xiamen Railway, this paper made the cause analysis, and then suggested a scheme of Bridge-Instead-of-Subgrade. This has guaranteed not only stability of the subgrade engineering, but also smooth progress of the construction of Fuzhou-Xiamen Railway.
