摘要
本文在综合厂址、近区域及区域地震地质资料的基础上,根据有关规范的要求,采用地震构造法、最大历史地震法和概率法分别计算了沈阳2×200兆瓦低温核供热站厂址的极限安全地震动SL-2,计算结果分别为200Gal、125Gal和170Gal。取三者最大值,厂址SL-2应当是200gal。厂址基岩地面运动SL-2水平向加速度反应谱取确定性法和概率法计算曲线的外包线作为用于厂址的基岩加速度反应谱。
Based on synthetic analysis of regional and near-regional seismogeological data, the ultimate safe ground motion (SL-2) for the site was obtained by the seismo-tectonic method, the probability method and the maximum historical earthquake method in accordance with the rules of the nuclear safe guidelines. The calculating results are 200Gal, 170Gal and 125Gal respectively. We take the maximum value of them as ultimate safe ground motion(SL-2). We also think it is suitable to take the enveloping curve of the horizontal acceleration response spectra corresponding to SL-2 based on probabilistic method and deterministive method as the acceleration response spectra of the basement rock site.
