摘　　要：抽水试验是一种常用的有效测定渗透系数及影响半径的试验方法,对基坑降水、坝基渗漏等工程问题具有明确的指导意义。但因计算中水文地质参数的选择不同,最终的计算结果往往会出现偏离实际工程情况。文章就牡丹江江心岛某工程抽水试验的数据进行分析计算,并对单孔抽水法,多孔抽水法,水位恢复法及颗粒分析法等计算方法的可靠性进行分析论证。Pumping test is a kind of common and effective test method to determine the percolation coefficient and influence radium,having a clear guiding significance for the project questions about precipitation of foundation pit and seepage of dam foundation. But,the final calculation results always tend to deviate from the actual engineering situation because different choices on hydrogeological parameters during calculation. Data about pumping test of a project located on the central island in Mudanjiang are analyzed and calculated,and the reliability of various methods including single hole pumping method,porous pumping method,water level recovery method and dust analysis method are analyzed and demonstrated in this paper.
