摘要
大岗山水电站坝址区设计地震峰值加速度达到557.5 cm/s2,大岗山拱坝的最大坝高达210 m,其地震动响应规律复杂,通过前期勘测设计阶段系统、全面的研究,抗震方面存在的有关问题在可行性研究阶段已基本明确,采取的相应工程措施满足可行性研究阶段工程抗震的要求,大岗山拱坝的抗震安全性能够得到保证。
The design peak seismic acceleration within the site area of Dagangshan Hydropower Station is to reach 557.5 cm/s2 with a complicated law of seismic dynamic response,moreover,the maximum height of the arch dam for the hydropower station is to be 210 m.Therefore,a systematic and comprehensive seismic study on the dam is just made during the phase of the early-stage investigation and design for the project,and then,the related seismic problems are clarified and the relevant engineering countermeasures to be adopted therein can meet the seismic requirements for the feasibility study concerned as well.Therefore,the seismic safety of the arch dam for Dagangshan Hydropower Station can be surely guaranteed.
