结合锦赤铁路高填方路基沉降观测工程实例，分析了传统法观测路基沉降的弊端以及单点沉降计在高填方路基沉降观测中的应用，结合现场试验进行了路基沉降观测数据分析，认为高填方路基沉降最基本原因是路堤自身重力，为今后高填方路基稳定性分析提供了技术参考。实践证明，单点沉降计的应用解决了传统观测法所存在的精度不高、操作困难的问题。

With the observation of the settlement of the high-filled subgrade of the Jinzhou-Chifeng Railway as a practical exam- ple, the malpractice of the observation of settlement by traditional methods and the application of the single-point settlement meter to the monitoring of the high-filled subgrade are analyzed in the paper, upon the basis of which the obtained observation data on the settlement of the high-filled subgrade are studied with some site tests performed for the sake of comparison. It is concluded from the analyses that the most fundamental cause for the settlement of the high-filled subgrade lies in its own gravi- ty, the conclusion of which may serve as a technical reference for the analysis of the stability of other high-filled subgrades in the future. Practice proves that the application of the single-point settlement meter helps solve the disadvantages of traditional observation methods being short of precision and difficult in operation.
