摘要
提出一种地下水流系统有限元与卡尔曼滤波耦合的模拟算法。该算法考虑了地下水运动的确定性和随机性特点 ,可用于地下水监测网的优化设计。应用该算法对大庆地区地下水动态监测网进行了分析 ,结果表明 ,大庆地区现有地下水位动态监测网难以达到监测目标 ,其最优地下水位动态监测网应由 88个监测孔组成 ,监测频率为每月 1次。
In this paper, an algorithm of coupled finite element and Kalman filtering is proposed based on the consideration of deterministic and stochastic behaviors of groundwater movement and is applied to optimal design of groundwater regime monitoring network in Daqing region. This algorithm is used to analyse the groundwater dynamic monitoring network in Daqing region. The results indicate that it is difficult to implement monitoring objective for existing groundwater regime monitoring network in Daqing region and its optimum groundwater monitoring network should consist of 88 observation wells with observation frequency of one time per month.
