摘要
Abstract
The foundation uplift pressure of a RCC gravity dam is becoming large after years of operation. To timely take ap-propriate measures, the RCC gravity dam safety monitoring data of the uplift pressure in recent years were reviewed, analyzed and evaluated. The causes for the high foundation uplift pressure were analyzed in terms of uplift pressure coefficient, openings, uplift pressure distribution and variation by using the monitoring data of osmometer and measuring weir, and the measures of increasing drainage holes to lower the foundation uplift pressure in time were put forward accordingly. After taking a series of measures, the gravity dam was in safe condition, and the elevation of foundation uplift pressure did not affect the dam safety from the overall perspective.关键词
