水封的密封跌落效应研究
Research on the Sealing Drop Effect of Water Seals
摘要
Abstract
This study investigates the sealing failure of high-head gate seals,revealing the influence mechanism of the drop effect on sealing performance through constitutive characteristic testing and mechanical modeling of the water seal.Based on the sealing mechanical model considering the drop effect,the Pmax-P'action relationship and the τintrinsic-Δultimate are used to characterize the effectiveness of the water seal from the perspectives of mechanical pressure-bearing performance and material constitutive performance,respectively.Among these,the τintrinsic-Δultimate is more operationally useful for clarifying the impact of the drop effect on the sealing effectiveness of the water seal.The correlation characteristics of the experimental data indicate that the τintrinsic-Δultimate generally decreases with an increase in compression ratio ε and shows a significant drop effect when ε>15%,resulting in a sharp decline in the sealing effectiveness of the water seal.This finding provides important reference data for predicting the ultimate pressure-bearing performance of in-service high-head gates.关键词
