Abstract

Uplift pressure within the dam foundation is crucial for maintaining the stability of gravity dams and serves as a pivotal metric in evaluating dam safety. This study evaluates the uplift pressure characteristics of the Wanmipo Hydropower Station's dam, drawing upon years of accumulated monitoring data. Using process curve analysis, spatial distribution, and statistical modeling, we conducted an in-depth analysis of the uplift pressure data from both qualitative and quantitative perspectives. We also evaluated the efficacy of the dam's grout curtain in decreasing seepage. Our findings reveal that the temporal and spatial variations of uplift pressure are within expected norms, the grout curtain effectively mitigates upstream water levels, and seepage within the dam foundation has reduced after years of operation.
