摘　　要：本文就三门峡水利枢纽溢流坝Ⅱ段测压管水位异常问题,进行了Ⅱ坝段测压管水位异常现象、水位和水温的关系的研究和分析,进行了充、放水试验,得出了测压管水位异常升高原因是2号底孔存在贯穿性裂缝所导致的结论,采取了对裂缝采取凿槽嵌补的封堵措施,得到了Ⅱ坝段测压管水位未再异常升高的结果。This paper is on the abnormal water level of the piezometric tube in the II section of the overflow dam of Sanmenxia Water Conservancy Project.The relationship between the abnormal water level of the piezometric tube in the II dam section and the water temperature is studied and analyzed,and through the filling and discharging tests comes out the conclusion,which the abnormal increase of the water level of the piezometric tube is caused by the existence of penetrating cracks in the No.2 bottom hole.Through the chiseling and filling the cracks as the sealing mearsures,and the result that the water level of the piezometric tube in the II dam section did not increase abnormally was obtained.
