模型优适度辨识含水层补给进口的原理、方法和应用

本文阐述了一种新的研究成果——用模型优适度寻找含水层主进水口位置的原理、方法和应用。模型优适度作为衡量地下水模型场势与原型(矿区)场势相似拟合程度的量度,它凭借含水层地下水场势对源点的响应差异,判别模型源点位置与原型源点位置是否一致、接近或偏离。本文给出了模型优适度的计算公式和用统计分析方法对动态矩阵施行标准化的公式推演过程。通过多次模拟试验,绘出优适度的等值线图,为华北某矿圈定含水层补给范围,进行注浆堵水,大大地降低了矿井涌水量,在实践应用中获得初步成功。

Modelling Analogy Coefficient for Locating Aquifer Inlet

Briefed in this paper is a new research fruit, the coefficient of modelling analogy in locating the chief inlet to an aquifer, together with its principle and application. This coefficient is the degree of similarity between the potential of the ground water model and that of the prototype ( a mining area). By virtue of the difference in response of the underground water potential in the aquifer to its source point, the modelled source point can be found to be coincident with, or in the vicinity of, or away from that of the prototype. The coefficient is obtained by using, and a standarized equation for a dynamic matrix is developed through statistical analysis. Simulations are done and an isogram for the coefficient is established, with the help of which preliminary success is made in a coal mine of North China in greatly reduing the water gush by defining the aquifer recharge zone and thereby grouting to block the water
