为了从含水层本质特征定量评价含水层富水性及其影响指标的相关性,根据研究区含水层沉积和构造特征,并结合地质及水文地质补充勘探资料,确定了影响含水层富水性的指标包括含水层砂地比、含水层厚度、粗砂岩厚度、粗砂岩层数、断层分维值和褶皱分维值,采用灰色关联度对6项影响指标与含水层富水性的相关性进行了研究。通过计算分析,对含水层富水性影响由大到小依次为断层分维值、含水层厚度、含水层砂地比、砂岩层数、粗砂岩厚度和褶皱分维值。说明了含水层富水性受到构造的影响较大,但是沉积特征同样对含水层富水性起到了重要的影响作用。在对含水层富水性进行分析的过程中,考虑到构造控水的同时,含水层沉积控水作用同样应该受到重视。
In order to quantitatively evaluate the correlation between the water-bearing characteristics of aquifers and their impact indicators from the characteristics of aquifers, the indicators that affect the water-bearing capacity of aquifers are determined according to the sedimentary and tectonic features of aquifers and the geological and hydrogeological supplementary exploration data Aquifer sand ratio, thickness of aquifer, thickness of coarse sandstone, coarse sandstone, fractal dimension and fractal dimension of fractures, and the correlation between six influencing indexes and water-bearing capacity of aquifer was studied by gray relational degree. According to the calculation and analysis, the influence of aquifer richness from largest to smallest is fault fractal dimension, aquifer thickness, ratio of sandstone to aquifer, sandstone, gritstone thickness and fold fractal dimension. It shows that the water-bearing property of aquifers is greatly affected by the structure, but the sedimentary characteristics also play an important role in the water-richness of aquifers. In the analysis of aquifer rich water, taking into account the structure of water control at the same time, aquifer sedimentary control of water should also be taken seriously.
