摘要
重力勘探的近区地形改正,一般通过典型剖面的试验来确定是否需要改正,并采用简易地改仪实测地形改正值。典型剖面试验难免以偏概全,实测的方法耗资费力。本文通过对典型物理模型的理论计算及一定数量实测值的统计分析,提出了一套参考数据及近区地形改正的方法,既简便,又节约费用。
Generally based on surveys of typical geological section,it can be determined that if the shortrange terrain correction of gravity exploration is necessary or not.And the numerical values of terrain correctioncan be obtained by simple terrain correction instrument.But the surveys of typical section are hard to be all rightand the cost is high.After calculation of physical models and statisties of a quantity of determined numericalvalues,the author proposed a series of parameters as well as a simple and low costed method of short rangeterrain correction.
