地表移动观测站实测资料数据缺失的修复研究

Research on Repairing the Missing Data of the Surface Movement Observation Station Measured Data

地表移动观测站的实测资料中测点的观测数据(如高程数据)缺失,不仅影响实测资料的完整性,更会对地表移动规律和参数分析产生较大影响,有必要对其修复方法进行研究。本文以某矿区A工作面地表移动观测站完整的实测资料为基础,利用插值和曲线拟合的方法对假定缺失的数据进行修复分析,通过研究表明,利用上述方法对处于非下沉关键期的缺失数据进行修复是可行的。

The observation data（such as elevation data） missing of surface movement observation,not only affect the integrity of the measured data,but also have great impact on the surface movement law and parameter analysis,it is necessary to study the repair methods.This paper based on the full observation data of the A working surface in a mining area,used the method of interpolation and curve fitting to repair the missing data.The study shows that using the above methods to repair the missing data in the subsidence stage is feasible.
