相关分析在电测深资料解释中的应用

在电测深区域地下水资源勘查中,为能充分利用区域内的钻孔抽水试验资料,本文从数理统计的角度出发,采用一元线性回归的方法,对电测深资料进行电性参数和水文地质参数解释,可以获得较电阻率反演法之外的收获,如可获得孔隙含水层等厚图、等渗透系数图、涌水量平面图等成果图,为评价水文地质单元内地层的赋水性及了解其它水文地质参数提供宝贵的资料。

APPLICATION OF CORRELATION ANALYSIS IN DC SOUNDING DATA INTERPRETATION

During the regional groundwater resource exploration using the electrical sounding method,in order to make full use of borehole data in the range of exploration area,this paper discussed the interpretation of electrical and hydrological parameters for DC sounding data u- sing one-rank linear regression method from the viewpoint of statistics,so we can get much more information than that of resistivity inversion method.And some figures can be gotten, like contour map of pore aquifer area,permeability coefficient map,plan of outflow rate etc, which can provide some valuable data for appraising the water content of hydrological geology and learning hydrological geology parameters.
