摘　　要：本文介绍了稳态强度有关特性，在此基础上，建议了因考虑稳态强度而导致地震液化后土体的液化区渐进扩散的计算方法．并利用某土坝作为算例，进行了计算，得到结果合理，为深入研究地震后的土体液化区扩散，从而进一步研究堤坝稳定性分析打下基础．A numerical method is presented to investigate the post liquefaction diffusion of liquefied zone in soil due to the steady state strength. As an example, the diffusion of liquefied zone in an earth dam body and its foundation is analyzed by using the proposed method. On this basis, the diffusion of liquefied zone in soils after earthquake and the stability of embankment as well as earth dam can be further studied.
