摘　　要：本文指出利用群孔抽水试验求取水文地质参数时,应注意的几个问题,即观测孔降深的计算应考虑区域地下水的天然动态趋势;应考虑水文地质边界的影响,正确使用地下水流动力学公式;加强基本条件判断的严谨性和准确性。针对这些问题,讨论了韩冬梅等发表在《工程勘察》上的一篇关于煤田烧变岩群孔抽水试验的案例论文,指出了其中应该纠正的不妥之处。In analysis on the well-group pumping tests for the estimation of hydrgeological parameters,several problems should be paid attention which include that the trends in natural groundwater level changes are needed to be considered in calculating the drawdown in observation wells; the hydraulic equations of groundwater flow should be applied in a correct way where the boundary effects are considered; the basic conditions should be strictly and accurately determined. Concerning on the problems,a previously paper published in Geotechnical Inveseigation Surveying with a case study on the well-group pumping test in burned rocks is discussed,and some wrong places in the case study are pointed out.
