摘要

我国大坝建设蓬勃发展,许多世界级的超高坝已经或即将在西部高地震烈度区域建设。通过对典型工程震害案例进行分析表明,在避开主要地质缺陷、合理设计、认真施工的基础上,混凝土坝具有较强的抗震性能。但在水电工程抗震研究、设计中,混凝土材料动态特性、坝体与无限地基动力相互作用、坝体与库水动力相互作用、坝体横缝动接触等问题仍需要进一步深入研究,相应的设计规范也有待进一步修正。
Many world-class extra-high dams have been or will be constructed in western mountainous area of China where the seismic intensity is high.The analyses on typical earthquake damage cases show that the concrete dam has good earthquake-resistant performance after avoiding major geological defects,reasonable design and careful construction.But in the seismic study and design of concrete dam,some problems,including the concrete material dynamic characteristic,the dynamic interaction between dam and infinite foundation,the interaction between the dam and reservoir water and the dynamic contact of transverse joints,still need further study,and the corresponding design specification needs to be further revised.
