| Abstract: | The variation relations between seepage pressure change, seepage pressure coefficient, and water level of the reservoir are analyzed in detail. The seepage pressure coefficient for observation hole U 7 1 , which is in front of curtain grouting, approximates to constant, with a synchronous relation to reservoir water level. The relations between seepage pressure distribution of dam foundation, the feature of impervious sediment cover in front of dam, curtain grouting, distribution of fissures in seepage fault zones are analyzed. |
