在实践中经常会遇到比较复杂的水文地质条件,或者裘布衣假定不成立,或者计算太过复杂,现有的规范、手册等未给出这些条件下稳定流抽水试验渗透系数的求解公式。为此,本文运用汇源理论和镜像法,结合具体工程实践,推导了在无限厚含水层和不同边界条件下非完整井稳定流抽水试验渗透系数的计算公式,通过工程勘察实践验算,验证了计算方法和公式的合理性。
In practice, we often encounter more complex hydrogeological conditions, or the assumption of fur and cloth is not valid or the calculation is too complicated. The existing specifications and manuals do not give the formulas for calculating the permeability coefficient of steady flow pumping tests under these conditions. Therefore, in this paper, using the Huiyuan theory and the mirror method, combined with the specific engineering practice, the formula for calculating the permeability coefficient of the steady flow pumping test of the nonholonomic wells under infinite thickness aquifers and different boundary conditions is deduced. Through calculation of engineering investigation, The rationality of the method and formula.
