河北省邢台市奥陶系灰岩岩溶地下水资源计算与评价

The Calculation and Evaluation of the Ground—Water Resources in the Ordovician Limestone Karst in Xintai Hebei

随着国民经济的发展,邢台市由一个古老的城市发展成为以机械、煤炭、能源为主的中等工业城市,对地下水资源的需求量日趋增多,正确计算和评价本区奥陶系灰岩岩溶地下水资源,迫在眉睫。本文所论述的百泉泉域奥陶系灰岩地下水资源的计算,是建立在对区域地质、水文地质条件分析研究的基础上,对22年的补给量进行计算。采用了综合渗入系数法、统计实际排泄量法和地下迳流系数法三种方法。三种方法计算结果接近,故本次以三种方法计算结果的平均值,作为本区奥陶系灰岩岩溶裂隙地下水开采资源,多年平均开采资源为10.6666米~3/秒。

With the development of the national economy, Xintai City, being poorer in industry, has now become a middle-developed one, which is characterized by mechanical, coal and energy industry, and the need for ground-water resources is increasing daily. Thus it is urgent to deal with the calculation and evaluation of the limestone karst in Ordovician strata of this region. In the course of the calculation of the ground-water resources in the Ordovician limestone karst, Baiquan region, we used three methods, namely the synthetic infiltration coefficient method, the statistic actual grainge, and the undergrour, d runoff coefficient. The results calculated by means of these three methods were approach. The average data of them may be used as the ground-water winning resources in the Ordovician limestone karst in this region, and 10.6666 M^3/S as the average winning resources of years. On the basis of the analysis of the regional geology and the hydrogeological condition togather with more consideration of the ground. water moving character and of the measurement data of the river infiltration flow, we calculated the recharge volume in the last twenty years.
