摘要
从水均衡原理出发 ,建立了时变参数的承压水漏斗水位预报的动态模型 ,采用多层递阶方法求解模型 .实例表明 ,文中模型预报效果较好 .该模型能反映漏斗中心水位的动态特性 ,且不要求均衡区承压含水层为各项同性的均匀透水介质 ;既适用于预报 ,也可用于漏斗区水资源的规划设计和管理等 .模型具有广泛的推广应用价值 .
A dynamic model of time-dependent parameter is developed for stage forecasting of confined water cones based on the groundwater balance principle, and the multi-layer recurrence method is used for finding the solution. An example shows that forecast result by the model is effective. The model can reflect the dynamic characteristics of the water stage at the cone center, and it does not require artesian aquifers in balance regions to be of homogeneous media. The model can be used for both forecasting and water resources planning & management in cone regions. Therefore, the model can be popularized.
