摘　　要：界定铬渣堆积范围对于场地环境的维护和管理具有现实意义。工业生产过程中燃烧产生尾渣的磁化率是土层的几十倍,为高精度磁测在铬渣污染场地中的调查提供了前提条件和物理基础。文章采用高精度磁测对青海海北某一铬渣堆积场地进行调查,根据异常曲线的特征和定性拟合解释剖面,判定为铬渣填埋体为三度体,可近视看成为球体,球体的直径为5.8 m,计算得出该处铬渣的堆积体积约102 m3,与传统的地质钻探探测效果基本吻合,误差在5%以内。Determination of area of chrome waste is helpful for the field environment maintenance and management.The susceptibility of industrial process would be raised several times by combustion,and the anomalies are the precondition and physical basis for the investigation of chrome waste by high precision magnetic survey.A chrome waste site to map the area in Qinghai was investigated.According to characteristics of abnormal curves and qualitative interpretation of profile fitting, the chromium residue was determined as three dimensional body,which can be regarded as a sphere,with diameter of 5.8m, and the volume was calculated as about 102m^3.It is consistent between the results of high precision magnetic survey and traditional geological exploration,with an error lower than 5%in determining the area.
