ABSTRACT
In order to overcome the shortcoming of one dimensional (1-D) infinite slope stability analysis theory, U. Mello et al. developed a two dimensional (2-D) 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. With the solution for the stress state of infinite slope with advanced 2-D slope stability analysis theory, it is possible to investigate the slope stability of infinite slope. Considering the limitations of theory of 1-D infinite slope stability analysis, Mello et al had established a 2-D analytical solution for infinite slope. In order to overcome the shortcomings of 1-D infinite slope stability analysis theory, Mello & L. Pratson developed a theory of 2-D infinite slope stability analyses, which provides a framework for understanding the general geometry and relative motion of mass movements not addressed by 1-D infinite-slope analysis or the empirical 2-D analyses.
