Abstract

The unsaturated seepage theory was employed to calculate the seepage field of geomembrane faced sandy-gravel dams with different heights. The influences of the location and size of defect on the phreatic line and seepage flux of dam were analyzed particularly. The results revealed that the change trends of the phreatic line and seepage flux of dams with different heights are basically the same. However, the height of phreatic line and the seepage flux both decrease with increasing defect location in geomembrane. In addition, the size of the defect has little influence on the phreatic line and seepage flux.
