AB - Associated with slope stability, cohesion, and friction angle which are the  most factors that can affect the slope failure, Investigation studies in  geotechnical structure analysis establish that the dilatancy angle, y, is  rarely acceptable in slope stability analysis, and when it considers the  process is poorly sophisticated and simplistic. The paper describes two  numerical slope stability analyses of a homogeneous soil with a plane strain  model, to study the influence of dilation angle through different friction  angle ranges (20, 25, and 30). The analysis used an immutable friction angle  with variable dilation angle, results show that the safety factor increases  gradually with the increase of dilation angle and dramatically decreases  when the dilation angle is close to the friction angle, which means the  dilation angle, y, affect the safety factor through slope analysis. It is  very significant to check out the scrupulous value of dilation angle, y,  when dealing with associated and non-associated soil parameters. In  geotechnical and thermal analysis, dilation angle can affect the volume  change as well as a safety factor.
