摘要
以现场调查资料为依据,根据长期的裂缝监测资料,对湖南镇水电站导墙裂缝变化规律进行了研究,并用有限元分析校核洪水位时溢流面及墩后动水压力对存在裂缝的导墙应力状态的影响,从而对湖南镇水电站导墙进行结构安全性评价。
Based on local survey data and long-term monitoring data of cracks, the article analyses the change rule of cracks and the crack＇s stress state of the guide wall of sluice way under the hydrodynamic pressure during flooding ,rely on three-dimensional finite element, evaluating the security of the guide wall in Hunan zhen Hydropower Station.
