Study on Environmental Materials with Analysis of the Hydraulic Connection Between Downtown and East and West Suburbs in Jinan, Shandong Province of China

摘要

The recognize of hydrogeological conditions is not clear, and there has always been states of dry up in Jinan spring. This paper divides jinan monoclinic structure into three primary ground water systems, and three secondary karst water subsystems based on the groundwater system theory. On that basis, reveal the recharge source of Jinan springs through the analysis of regional aquifer medium and hydrodynamic characteristic, further confirm that the hydraulic connection of western suburb is better close with downtown than that of eastern suburb by regression analysis method, so the recharge well can be designed and allocated in western suburb to recharge groundwater. This paper introduces inverted filter's materials needed by recharge well such as quartz sand and limestone, as well as advantages and disadvantages of them. These conclusions provide scientific basis for spring protection and the mining of karst water with high quality.
