Dam Seepage Monitoring Data Analysis of Yuqiao Reservoir

In this paper,dam body and dam foundation seepage monitoring data,vertical and horizontal profile of dam seepage field,statistical model of seepage water level,potential process line in dam foundation,dam seepage flow and so on for Yuqiao reservoir are analyzed respectively.Results indicate that:in the left monadnock part,gravel stone layer exists in dam foundation,along with unconspicuous anti-seepage effect of grouting,high dam saturation line,and strong correlation of dam foundation seepage water level and reservoir water level;in the inverted earth part,correlation of dam foundation seepage water level and reservoir water level is strong,and anti-seepage effect of jet grouting wall fails to reach the expected goal;in the right light rolling compaction part,correlation of dam foundation seepage water level and reservoir water level is strong and potential is high;in the contact part of water release tunnel and dam body,there may be a contact leakage hidden danger;seepage of other dam parts are normal.Analysis conclusion in this paper provides an important basic support for dam seepage safety evaluation of Yuqiao reservoir.
