摘要
水文地质数值模拟中参数估计的方法较多,但大多对非线性问题的适应性较差。在陕西省靖边县四柏树水源地三维水文地质数值建模中,选用独立于模型本身的非线性系统加权最小二乘方法,对模型中的水文地质参数(K,μ,Ss)进行最优化估计,取得了较好的效果。
There are many methods for parameters estimation in hydrogeological numerical model, but many of these are not suitable for non-linear problem. In 3D hydrogeological model of Sibaishu water source place in Jingbian county, the weighted least require method for non-linear system that independent the model was selected for optimal estimation on hydrogeological parameter (K,μ,Ss), and had achieved batter effects.
