高精度磁测在圈定垃圾填埋场范围中的应用

Application of High-precision Magnetic Measurement Method for Mapping the Scope of Landfill

研究垃圾填埋场中的地磁特性,界定垃圾填埋场边界有助于场地环境的维护和管理。本文采用高精度磁测对临川区展坪乡垃圾填埋场进行调查研究,利用CZM-3型质子磁力仪探测填埋场地的地磁场,对整个测区的ΔT数据进行数据的预处理(网格化文件数据、空白区填补、数据扩边)、空间域位场分离(圆滑滤波)、空间域位场转换(主要有化极和向上延拓)。通过对资料分析与处理解释,划分了填埋场的磁异常区域,圈定了填埋场的填埋边界及其范围,其面积大约为3000m2。

Research on the magnetic properties of sanitary waste landfill and determination of board of sanitary waste landfill are helpful for the field environment maintenance and management.This paper uses the high precision magnetic survey to investigate the sanitary landfill in Linchuan Zhanping Town.With CZM-3 protons magnetometer to detect landfill of magnetic field and process the ΔT data of the whole survey area（The file data grids,filling blank areas,data expansion）;spatial field separation（smooth filter）;spatial field transfer（pole and upward continuation）.By analyzing and processing the information,we divided the magnetic anomaly of landfill and selected the boundary and scope of landfill,which is about 3000m2.
