确定潜水含水层系统参数的Boulton-RAGA方法

Boulton-RAGA method for identifying unconfined aquifer parameters

摘要: 在对考虑迟后排水的N.S.Boulton第二潜水井流模型解析解分析的基础上，将复合高斯求积法和具有随机搜索寻优特性的实数编码加速遗传算法(RAGA)相结合对其进行优化求解，提出了确定潜水含水层系统参数的Boulton-RAGA法。以计算实例表明，Boulton-RAGA法可以取得很好的求参效果，并且与传统方法比较，方法简单，快速，不需要分抽水时间——降深过程的前、后段进行参数确定，大大简化了潜水含水层的参数确定过程，对于缩短抽水时间确定含水层系统参数具有重要的意义。

Abstract: Based on analyzing the solution of the Boulton model introducing the concept of delayed yield and combining the Gauss Integral with Real coding Accelerating Genetic Algorithm(RAGA), a new method was presented——Boulton-RAGA for identifying unconfined aquifer parameters. By actually applying, this approach can be used to quickly identify the aquifer parameters, and the obtained parameters were proved to have good accuracy.
