ABSTRACT 



General solutions for the failure surfaces in slopes where the 

 assumptions of the infinite slope theory are valid have been de- 

 rived. The solutions are applicable to layered systems and to any 

 seepage conditions provided that both layering and ground water 

 flow are parallel to ground slope. It is concluded that the infinite 

 slope theory is of limited appUcability unless modified. A modi- 

 fication to enable transition from the active to passive stress 

 states is suggested.
