短水准资料中的降雨干扰相当可观.本文详细讨论了这种干扰的影响机制和影响特点,尝试用褶积运算方法建立单位降雨量影响模式和降雨总影响模型,并提出运用褶积滤波方法消除测值中降雨影响的具体方法.作者以新丰江测量站的资料为例进行了整套计算。结果表明,此模式能真实地再现资料受降雨影响的情况.用此法消除降雨影响后,测值恢复了正常的年变化形态,提高了资料的分析使用价值.
The rainfall disturbance in short-level data is very considerable.This paper discusses the influencing mechanism and influencing characteristics of this disturbance in detail, and tries to establish the unit rainfall effect model and the total rainfall impact model by the convolution operation method, and proposes to use the convolution filter method to eliminate Specific methods for measuring the impact of rainfall.The author takes the data of Xinfengjiang Survey Station as an example to carry out a complete set of calculations. The results show that this model can truly reproduce the data affected by the rainfall.Using this method to eliminate the influence of rainfall, the measured value regains the normal annual variation and enhances the value of the data analysis.
