Slope Geometry Survey
Slope Stability
In this laboratory project, I practiced analyzing highway embankment using GeoStudio 2012. A highway embankment is built in order to avoid the change in level. In this model, the embankment was constructed on a layer of soft clay and I needed to use GeoStudio 2012 to determine the location of the critical slip surface and the factor of safety. There are basically eight steps to analyze a new model using GeoStudio 2012. First is to start a new project, then, set the analysis options in KeyIn menu, next is to define the work space in Set menu. After which, set the axes propertied; define the material properties; set the problem geometry; draw the entry and exit points of the critical circle. After finishing all the setup, we are
able to start analyzing the model. By following the steps, I got the Factor of Safety equaled to 0.916, which was a failure design since the F.S. was less than 1. To re-design the model, I lowered the water table, and it turned out that the Factor of safety would increase as the water table decreased. In this case, I lowered the water table for about 2 meters, and the Factor of Safety rose to 1.011. Another way to increase the F.S. is to decrease the slope. Personally, I think GeoStudio is strong and useful software that will be used a lot in the field. It will save a lot of time by analyzing the model on computer rather than by hand calculations and it provides us a straightforward pictures showing how the slope will fail etc.
