摘　　要：为了解长距离输水管线上输水设施的运行状态,使工程运行安全有保障,需要对压力监测数据进行分析。本文以稳压塔为例,对其高程数据进行拟合。结果表明:a高程随时间变化的过程曲线,若是采集间隔为1s时则能够呈现一定的波动规律;b高程数据采用正弦波公式进行拟合,可得到可决系数较高的参数,为分析长距离输水管线的水力特性提供有力的理论基础。The pressure monitoring data should be analyzed in order to understand the operation state of water transmission facilities on long-distance water conveyance pipelines and guarantee the operation safety of the project. In the paper,the voltage stabilizing tower is adopted as an example for fitting elevation data thereof. The results show that：a the elevation process curve changing with time can display certain fluctuation rule when the collection interval is 1s;b elevation data is fit with sine wave formula,obtaining parameters with higher coefficient of determination,thereby providing forcible theoretical foundation for analyzing the hydraulic characteristics of long-distance wate conveyance pipelines.
