摘要
当地震引起土体的抗剪强度明显下降时,传统的拟静力法不适合用于坝坡的地震稳定性分析。针对上述情况汪闻韶提出了地震总应力法,该法可以考虑地震动孔隙水压力的影响。作者应用地震总应力抗剪强度法对马头电厂灰坝进行了地震稳定性分析,研究了提高贮灰坝地震稳定性的工程措施,为坝体的抗震设计提供参考资料。
When the earthquake caused soil shear strength decreased, the traditional pseudo static method is not suitable analysis the seismic stability of the dam slope. Wang Wenshao proposed the earthquake total stress method, which method considered the problem of the vibration pore water pressure. In this article, the author analysis horse head ash dam seismic stability by using the seismic total stress shear strength method, and improve the engineering measures of the ash dam seismic stabilityto provide reference data for the seismic designers.
