文章以有越流补给的承压水完整井流理论为基础,通过对有越流补给的承压水完整井流模型解析解的数值计算分析,界定了其井函数W(u,r/B)数值计算的近似积分范围,并且利用随机搜索寻优特性的实数编码加速遗传算法(RAGA)和复合高斯求积法优化确定有越流补给的承压含水层的水文地质参数。以计算实例表明,RAGA法可以取得较好的求参效果,并且与配线法、拐点图解法等传统方法比较,方法简单,充分利用了实测时间—降深数据,可以避免人工配线和图解的人为因素影响,简化了参数确定过程。
Based on the theory of complete well flow of pressurized water with overcurrent and recharge, the paper analyzes the numerical solution of the analytical solution of the complete well flow model of pressurized water with over-flow recharge, and defines its well function W (u, r / B (RAGA) and complex Gaussian quadrature method are used to determine the hydrogeological parameters of confined aquifers with over-flow recharge. The calculation example shows that the RAGA method can obtain better effect of seeking parameters, and compared with the traditional methods such as wiring method and inflection point method, the method is simple and makes full use of the measured time-depth data to avoid manual wiring and illustration Of human factors, simplifying the parameter determination process.
