济南张夏组灰岩岩溶地下水供水潜力探讨

Study on Potentiality of Karstic Underground Water Supplyment in Limestone of Zhangxia Formation in Jinan City

济南南部广布巨厚张夏组灰岩,其中赋存优质丰富的岩溶地下水。出露众多泉水,其流量为800～8000m3/d。该文通过简述济南地区张夏组灰岩岩溶地下水的赋存条件与水文地质特征,概略计算与评价其资源量,论证开发利用这一新水源的可行性,以期为济南供水与保泉开辟新途径。

Thick limestone of Zhangxia formation distributed widely in south of Jinan city, which developed rich karstic underground water with good quality. Many springs exposed in this area with the flow amount of 800 8000m^3/d. Occurrence condition and hydro - geological characteristics of karstic underground water in limestone of Zhangxia formation in Jinan city are briefly introduced in this paper, resource amount is calculated and evaluated, and feasibility for using and developing this new water sources is analyzed as well. Thus, it will provide new way for water supply and springs protection.
