基于低渗透性含水层的微水试验,提出了利用试验资料计算含水层水文地质参数的解析方法,推导了其解析表达式。该解析方法既考虑了水位降深和时间等参数,也考虑了将抽水量作为计算参数的已知量。用该方法确定含水层的水文地质参数,比用微水试验的配线法和水位恢复法具有更好的适用性,以某电厂地基抽水试验为例,用该解析法计算其含水层的水文地质参数,计算结果比较合理。
Based on slug tests on aquifers with low permeability, an analytical method for calculating hydro-geological parameter of aquifers with experimental data was proposed, and a corresponding formula was deduced. In this method, some parameters, including fall in water level, time, etc. were taken into account, and pumping rate was taken as a given value for parameter calculation. The application of the present method to calculation of the hydro-geological parameters based on the test data from foundation pumping tests at a power plant shows that the method is of high applicability as compared with the curve fitting method and water level recovery method.
