Abstract
In order to overcome the shortcoming of one dimensional infinite slope stability analysis theory, Mello et al. developed a two dimensional analysis theory. However, Mello?s theory cannot investigate the influence of earthquake on marine slope stability, which acts an important role on failure of marine slope. On the basis of Mello?s theory, an improved two dimensional infinite slope stability analysis theory has been proposed in this article. It is shown that the one dimensional infinite slope theory can be regarded as a special case of the new two dimensional theory. In general, the safety factor of slope got by the two dimensional infinite slope theory is lower than that by one dimensional theory. It is also shown that the slope stability influenced by combination of vertical and horizontal earthquake loading is much lower than that without earthquake. Meanwhile, further study should be carried out to investigate the abruptness of the slope stability influenced by different combinational modes of vertical and horizontal earthquake loading.
