鲁能运河电厂长沟岩溶水源地水位模拟预测

The Groundwater Level Forecast of Changgou Karst Water Resources Field on Luneng Yunhe Power Plant

长沟水源地是鲁能运河电厂供水水源地,通过预测水源地水位变化趋势,为电厂制定用水计划、及时调整开采布局提供依据。水位模拟预测是在五年长系列动态监测资料及地下水开采量调查基础上进行的,利用数值模型演练和预测了嘉祥单斜蓄水构造单元内在现状岩溶水开采状态下及增加20%开采量条件下的区域地下水流场变化特点,所模拟的曲线与实测曲线相吻合,所推算出的水文地质参数合理,为保证水源地合理、稳定、持续的开采提供了科学支持。

Karst water resources field of Changgou is the water supply sources of the Luneng Yunhe Power Plant. By forecasting groundwater level of water resources field, we can lay down projects of using water for power plant and adjust rational distribution of groundwater exploitation without delay.Groundwater level forecast is based on a long series water level dynamic monitoring data of 5 years and the surveys on amount of groundwater mining. By making use of numerical model, the authors performe and forecast the features of regional groundwater flow field change under the karst water exploitation status in quo and increasing 20% on water resources quantity mining in hydrogeology unit of Jiaxiang Monoclinal Store Water Structure. it is turned out that the stimulant curves of water level tally with the actual measurement, and the calculated hydrogeology parameter is reasonable, the forecast groundwater level is conservative in a way. The result provides a science basis on ensureing rational, steady and sustaining exploitation of karst water resources field.
