地面沉降数据中周期性影响因素分析

Analysis on periodical influence factors of surface ground subsidence data

基于地表沉降控制点的数据,结合兖州矿区的沉降实测资料,应用小波去噪的方法对累计沉降量进行滤波,并采用傅里叶变换分析的方法分析影响地面沉降的主要周期性影响因素的周期信息。

Base on the data of the surface ground subsidence control points,in combination with the surface ground subsidence measured information of a mine in Yanzhou Mining Area,the wavelet noise killing method was applied to filtrate the accumulated subsidence value and the Fourier conversion analysis method was applied to analyze the periodical information of the main periodical influence factors to the surface ground subsidence.
