摘要

为分析小浪底大坝的抗震性能,采用总应力法对斜墙坝型进行了二维和三维动力有限元计算,然后对改进后的斜心墙坝型进行了二维和三维有效应力地震反应计算。计算结果表明:斜心墙坝型的抗震性能优于斜墙坝型;对大坝稳定最为不利的地震工况是水库诱发地震,在可能发生最大烈度地震并假设坝基构成最为不利的情况下,小浪底大坝仅局部破坏,其整体稳定性是有保证的。
In order to analyze anti-seismic of the Xiaolangdi Dam,based on the total stress method,the inclined wall type of dam two-dimensional and three-dimensional dynamic finite element calculation was carried out.Then on the improved dam type namely inclined core wall type of dam two-dimensional and three-dimensional effective stress calculation of seismic response was completed.The calculation results show that,the inclined core wall type of dam anti-seismic is better than the inclined wall type of dam,on the stability of the dam,the most disadvantageous earthquake is reservoir-induced earthquake,in the maximum seismic intensity and the hypothesis of dam foundation constitute the most unfavorable circumstances,dam only partial is damaged and its overall stability is guaranteed.
