摘要

乌东德水电站地处亚欧大陆地震带,其抗震性能受到广泛关注。采用"静力设计、动力调整"方法进行大坝体形设计,并采用现行抗震规范规定的基本分析方法与非线性有限元法对大坝选定体形的抗震性能与抗震安全性进行分析评价,提出了大坝抗震措施和强震监测设计方案。研究结果表明,乌东德高拱坝在设计与校核地震作用下,坝体应力状况较好,与国内几座高拱坝相比,应力水平较低,横缝开度较小,坝肩抗滑稳定裕度大,大坝-坝基系统具有较强的极限抗震能力。
Wudongde Hydropower Station is located in the Eurasian seismic belt,and its seismic safety draws extensive attention.The method of "static design and seismic adjustment" is adopted in the design of the shape of arch dam.The basic analysis method specified by current seismic code and nonlinear FEM are used to analyze the seismic behavior and the seismic safety respectively.The anti-seismic measures and monitoring design scheme of strong earthquake are given.The results show that the stress status of Wudongde high arch dam is in a satisfying state under both design and check earthquake;comparing with other domestic high arch dams,the dam is proved to have lower stress level and smaller transverse joint opening,and the margin of anti-sliding stability of the abutments is relatively large and the dam-foundation system has strong limited seismic bearing capability.
