摘　　要：该文概述了国内外关于非填砾过滤器进水缝隙尺寸的规定,探讨了非填砾过滤器进水缝隙尺寸确定的设计标准及影响因素,在此基础上,对我国现行国标关于供水管井及勘察抽水试验孔非填砾过滤器进水缝隙尺寸的规定提出了修改意见。认为非填砾过滤器进水缝隙尺寸的规定,应根据设计标准的不同,综合考虑影响非填砾过滤器进水缝隙尺寸的因素来确定。The paper briefly introduced regulations of crack size of feeding water in non-flied gravel filter inside and outside of China. Design standards and effective factors for the filters are discussed. Some modifications of regulations of crack size of the filters for present Chinese GB water supply well and investigation water pumping test well are suggested. In conclusion the regulations of crack size of feeding water in non-filled gravel filter should be determined by different design standards combined with effective factors for the filters.
