The Dynamic Analysis And Numerical Simulation Of JINAN Spring Groups

Jinan is a famous city for the springs, just as the proverb describes "every household has springs". In the past decades, however, the springs' landscape declines gradually, with the social and economic development, and the illogical utilization of karst water. "With understanding to 1he Jinan springs present condition, and to researches on karst water, data were collecting and a right mathematics model was adopted to simulate and predict the dynamic change of Jinan karst water. Besides, measures were put forward to mine and protect Jinan karst water.The spring area for research was determined based on data from investigation on the spot and previous productioa The total area is about 2614.9km~2, which eastern boundary is Mashan Faults, western boundary Bucun Syncline, the northem boundary the Xiaoqing River and the 500-metre limestone roof, and the southern boundary the surface water divide. The physical geographical environment, hydrographic conditions, causes of formation and the dynamic change of spring groups spewing of the Jinan spring groups were introducedThe dynamic change model of karst water was established based on data processing with control function and optimizing genetic algorithms. The result indicated that the model had well steadiness.Tri-dimension mathematic model of karst water was established The simulation with the model was consistent with 1he fact. As mining capacity given, four kinds of mining projects were put forward to forecast 1he dynamic change of Jinan karst water with 1he model.Finlly, some measures were put forward to realize perennial spurting and resume special landscape of spring city, and to bring the mining project into effect.
