我国高土石坝抗震安全研究进展

摘要

Earth-rockfill dam was wildly used in hydraulic and hydropower engineering.Many of high earth-rockfill dams been built recent years were located in high earthquake intensity areas.And their seismic safety was the focus of the community and industry,as well as the difficulties and hotspots because of the complexity of earthquake and rockfill materials.Through a lot of studies and practice,China achieved series of research results about seismic safety and engineering measures of high earth-rockfill dams.Based on studies and construction practice,this paper briefly summarized the research results and technology progress of seismic standards,safety evaluation criteria,calculation analysis method and seismic engineering measures,etc.%土石坝在我国水利水电工程中被广泛采用,近年来建成了一批高土石坝工程,不少位于高地震烈度区,其抗震安全一直是社会和业界关注的重点.由于地震传播和土石材料的复杂性,高土石坝抗震安全也是科学研究的难点和热点.通过大量研究和工程实践,我国在高土石坝抗震安全及工程措施方面取得了一系列研究成果.本文着重从高土石坝抗震研究和建设实践出发,概要总结我国高土石坝的抗震设防标准、安全评价准则及计算分析方法、抗震工程措施等方面的研究成果和技术进展.
