Studing The Possibility Of Building The Underground Karst Reservoir In The Fu Jiaqiao Karst Area

City proper to new-type city propers that build are approved by the State Council fields lying fallow in rotation, and head factory Shandong Province's super-huge iron and steel enterprise steel Laiwu, Because water resource day by day outstanding imbalance between supply and demand, influence steel of fields lying fallow in rotation the development and steel urban constructions of head factory directly, Entrust by steel head factory of Laiwu and further investigate steel of fields lying fallow in rotation source of water the underground karstses of area store ink ability, It probes and build underground karst the possibilities of reservoirs namely retain the rainwash to the maximum extent, Strengthen at underground karst the supplies of reservoirs, at the earth' s surface water body directly with underground crack store water unite dispatcher by space by karst water-bearing stratum, It gives play to underground karst the regulating action for many yearses of reservoirs in line with" with mending and adopt definitely, Principle on adopt balance of mending", it accomplishes and increase the exploitation amounts of groundwater promptly make groundwater become more and more balanced. In order to keep Lu ZhongYan dissolving the good hydrogeological environment of area. At steel of fields lying fallow in rotation head factory enlarged reproduction and urban city of steel supply water the improvement of ability, Offer the scientific decision theory, for analysing and prove and build underground karst the feasibilities of reservoirs, This time adopt regional hydrogeology survey and draw, drilling, stability and flow and draw water many kinds of means of testing ,, radio isotope test dynamic observations groundwater etc steadilies,Study district the bridge source of water, The bridge ground of source of water of the Fu jiaqiao is one of the mosts important source of water ground of head factory of steel of Laiwu, Because excessive to exploit to groundwater, water table drop year by year, at source of water nearby form relatively heavy the groundwaters of ranges the funnel has fallen, Groundwater mend arrange extremely balanced, influence source of water the uses of field serious. Therefore cause the state of urban water supply to be becoming more tense .It divides into parts parts at regional geological structure, hydrogeological characteristic expound the fact the underground karst build storehouse terms by reservoir bridge by respects areas; The secondpart Have described producing water condition of the underground karst reservoir; The third part At the bridge reservoir surface water, underground karst unite dispatcher finite element number value the foundation and calculates of model by water; The fourth part At the bridge reservoir surface water, groundwater unite dispatcher transfer and hold ability analyse.This time adopts regional hydrogeology to survey and draw, the hydrology quality is explored on the source of water , the materials of prospect pit of and the underground karst, Combine the long series annual groundwater long view materials, proceed from water systematic view of karst, Study copies of district peculiar karst moisture structures, and , the earth' s surface wait till precipitation changing, balanced relation" waters"s between flowing atmosphere karst water crack terms border. And set up surface water , underground karst and water and unite dispatcher' s model , calculate through finite element number value, Science proves the underground karst of bridge of the Fu s reservoir and builds the possibility of the storehouse rationally. Adopt finite element methods and appraise the regional water resource of karst, to probing that it is very helpful to develop and utilize the water resource of regional karst of north karst. Relevant conclusions are as follows that this thesis is drawn :1. Underground karsts construct around the bridge source of water and stratum rock the controls of quality, It is an independent hydrogeological unit to form relative waterproof border that seals , The condition of...
