| 摘 要： | 针对水位观测井响应滞后问题,以井外壁水位为正弦函数变化为例,分析了观测井井壁内外的水力平衡条件,构建了井内壁观测水位与井外壁真实水位间的解析关系,采用优化的最小二乘法对观测数据进行最佳多项式拟合,获得了逼近于真值的数据。结果表明,该方法观测值再现真值合理,计算简单、精度高。

| Abstract: | The time lag problem of water level response of observation wells is investigated.Taking the sinusoidal water-level fluctuation function of outside well for an example,hydraulic equilibrium condition of inside and outside of observation well is analyzed.And the analytical relationship between observed water level inside well and true water level outside well is established.The optimal least square method is used to fit observed data with polynomial and the approaching true values are obtained.The results sh... |
