摘　　要：该文探讨了供水管井井水含砂量标准制定的依据和制定标准的影响因素 ,首次提出了“井水含砂量特征曲线” ,解释了井水含砂量标准控制指标的理论依据。概述了国内外井水含砂量标准的现状 ,并对分歧和争议问题进行了讨论。在大量管井施工及运行调查的基础上 ,提出了我国新的供水管井井水含砂量标准。The paper discussed formulated basis and causitive factors of well Water sand content standard in water supply pipe well.The “characteristic curve of well Water sand content” is introduced first time. It should be considered to take stable value of well Water sand content standard as theorectical basis for control index.Current situation of well Water sand content standards inside and outside China is outlined here and some differences and arguments for this issue are studied. Based on the great amount of pipe well construction and operation investigation a new well Water sand content standard in water supply pipe well is introduced.
