Analysis Method for Determinat ion of Hydrogeological Parameters by Pumping Tests in Multiple Wells at Different Time
摘要
Abstract
Trial method and special standard curve comparison applied for the hydrogeological parameters with data of pumping tests in multi-ple wells at different time feature the complicated calculation course, inevitable manual errors and severe diagram restriction.So, the opti-mum fitting method is applied.In range of the applicable engineering parameters and through the simple function substitution of Theis well function representedby stages, the water drawdown ratio method is applied based on the points selected from the drawdown-time curve of the pumping tests.Through the trimming and derivation of the flow functions of pumping wells at different time, a quadratic equation of one un-known which can be applied for direct determination of relevant hydrogeological parameters is obtained.The calculation course is simple, vis-ual and convenient to apply in practice.The precision analysis demonstrates that the maximum error is lower than 3.31% in the range of the applicable engineering parameters, fully satisfying the requirement of the calculation precision of engineering practice .关键词
