| 摘 要： | 针对我国大坝多建于高烈度地震区、坝基中存在软弱结构面和缓倾角裂隙等现象,以某重力坝为研究对象,探讨了在大坝坝底铺设铅加球墨铸铁对坝体动力反应及动力深层抗滑稳定性的影响。计算结果表明,坝底铺设铅加球墨铸铁可有效降低坝体动力反应,提高重力坝动力深层抗滑稳定性,这为提高大坝抗震性能提供了一种新的途径。

| Abstract: | Aimed at the phenomenon of China's dams mostly built on high intensity earthquake areas with weak structural surfaces and low-inclined cracks in the dam foundation,the influences of laying lead and nodular cast iron at the dam bottom on its dynamic responses and dynamic deep anti-slide stability were investigated by taking a gravity dam as an example.The results show that laying lead and nodular cast iron at the dam bottom can effectively reduce its dynamic responses and enhance its deep anti-slide stabilit... |
