| 摘 要： | 通过对北邢家水库大坝测压管观测资料进行综合分析，结合日常检查及地质勘察资料，判断出部分坝段粘土心墙存在填筑不均匀与防渗性能差的质量问题，发现了部分坝段存在坝体上游水位长期高于库水位的渗流异常现象，并将测压管资料绘制的大坝浸润线与渗流计算的浸润线进行对比，对理论计算采用的渗透系数予以验证。

| Abstract: | By data analysis of dam piezometer pipe,combined with routine inspection and geological survey of Beixingjia reservoir,the quality problem of bad filling and high permeability of the clay core wall was found.Also,the problem that dam upstream water level was higher than reservoir water level exists at some dam blocks.This paper compared the measured phreatic line to calculative phreatic line,and verified the seepage coefficient adopted in theory analysis. |

| Keywords: | piezometer pipe seepage phreatic line correlation |
