| 摘 要： | 本文深入研究了二维应力状态的地震动孔隙水压力计算方法，阐述了堤坝边坡地震液化失稳的特点和破坏型式，通过本文的分析论证和实例计算验证，说明堤坝边坡地震液化破坏的主要型式是边坡失稳；提出了堤坝边坡的抗震安全性能应由有效应力法动力稳定分析来判别的新论点。

| Abstract: | The criterion to evaluate embankment slope faifure due to earthquake induced liquefaction as well as its failure mode are described, and then, the calculation of dynamic pore water pressure and the analysis of dynamic stability are studied throughly in this paper.Analysis and numerical calculation show that the sloughing of slope is the main type of failure due to earthquake induced liquefaction.A new concept proposed is that the seismic stability should be determined by the dynamic stability analysis using the effective stress method. |
