摘　　要：大地电磁测深法已广泛应用于矿产资源勘查、工程地质、地震及地质灾害等领域。V8多功能电法仪是目前广泛使用的大地电磁数据采集系统,其随机配备的软件虽能显示或转换出采集到的时间序列文件数据,但没有时间域噪声分析处理功能。为开发与此系统相应的时间域噪声分析与处理系统,需对采集到的大地电磁测深原始时间序列数据进行分析。论文在分析大地电磁数据原始时间序列文件格式的基础上,明确了数据存储形式,根据参数特征,设计了原始数据读写算法程序,为大地电磁原始数据时间域分析及信噪分离提供了便利。Magnetotelluric sounding method has been widely applied to exploration of mineral resources such as shale gas and coalbed methane,engineering geology,and geohazard survey and so on.V8multifunctional electrical method is usually used as magnetotelluric data acquisition system,and its support software can display or conversion to the time sequence of file data,but there is no noise analysis processing functions in time domain.The magnetotelluric original time series data obtained must be analyzed in order to develop the system of the corresponding time domain noise analysis and processing system.This paper defines the form of data storage based on the analyzing the formats of magnetotelluric original time series data,and designs the program of raw data read and write algorithm according to its parameter characteristics.
