摘要:
为了研究不同井水位气压效率计算方法的原理及差异性,基于2019年2月1日至2020年7月28日云南高大井的气压与水位数据,使用Clark方法、Rahi方法、回归反卷积法和Acworth方法计算了该井的气压效率BE值,分别为:0.439 5、0.496 8、0.617 4和0.665 4,平均值为0.554 8。对比分析结果表明:Clark方法和Rahi方法的优点是计算简单方便,但是没有考虑时间滞后的影响; 回归反卷积法可以获得BE值随滞后时间的变化情况,但是极易受到降水、蒸散发等信号的影响; Acworth方法考虑了固体潮信号并且避免了降水、蒸散发等信号的干扰,但是该方法仅适用于承压和半承压含水层中。最后,根据4种方法的特点和适用性,对不同目的下的井水位气压效应分析给出了相应的建议。
Abstract:
On the basis of the data of barometric pressure and water level in Gaoda Well in Yunnan from February 1,2019 to July 28,2020,we calculated the well’s barometric-efficiency values with the Clark method,the Rahi method,the regression deconvolution method,and the Acworth method,and compared the calculated values from these four methods,so as to study the principles and difference of these four methods.The barometric-efficiency values were 0.4395,0.4968,0.6174 and 0.6654 respectively,and the average is 0.5548.The calculation of the Clark method and the Rahi method is simple and convenient,but the effect of time lag is neglected by these two methods.The variation of the barometric-efficiency values with lag time can be obtained by the regression deconvolution method,but this method is highly susceptible to the influence of signals like precipitation and evapotranspiration.The Acworth method takes into account the earth tide signal and avoids the interference of precipitation and evapotranspiration signals,but it is only applicable to confined and semi-confined aquifers.Finally,according to the characteristics and applicability of the four methods,we proposed suggestions for the selection of different methods of calculating the barometric efficiency under different conditions.
