| 本文总结介绍了高混凝土坝抗震安全评价方面的最新研究成果,包括震源破裂-传播介质-坝址峡谷地震动的超大规模数值模拟、坝体-地基-库水系统的非线性动力损伤开裂分析、混凝土动力特性的试验与细观数值仿真、基于性能的高坝抗震安全风险评估等内容。最后总结了高坝抗震研究的发展方向,并提出了综合考虑社会、经济、环境与工程的抗震安全风险评价体系研究思路。 |
| 英文摘要: |
| The state-of-the-art developments on seismic safety evaluation of high concrete dams is re-viewed, including:large-scale numerical simulation of seismic ground motion from source-media to dam canyons; nonlinear earthquake damage-cracking behavior of dam-reservoir-foundation systems; dynamic exper-imental tests and meso-scale simulation of concrete; and performance-based seismic safety risk evaluation of concrete dams. At the end, the development trends of earthquake-resistant of high concrete dams are concluded. |
