      桥梁的沉降变形控制是客运专线质量控制的重点，是决定桥梁承载力和保证线路运营后高平顺性的重要因素。阐释了郑西客运专线桥梁沉降变形观测控制方法，验证了设计、施工的合理性，并提出了相关建议，为今后类似工程施工提供借鉴。

英文摘要:

      Bridge settlement displacement control is one of the major tasks of quality control for passenger dedicated line. It is of radical importance to bearing capacity of bridge and to the control of railway operation performance. This paper, based on the bridge construction of Zhengxi passenger dedicated line, mainly expatiates on the methods of bridge settlement meas urement & control, so as to test and verify the rationality of the design and construction. Finally, some suggestions are pro posed, which may be used as reference for other similar works.
