Abstract

One of the most important aspects of design is the geometry that a road cross section must adopt after the earthworks necessary for the construction of a road. Therefore, slope stability has become the key element to control. The present investigation is
It focuses on defining safety criteria regarding the height and inclination that a road cross-section slope must present, in the presence of four types of chosen materials, fractured shale, silty sand, firm clay and expansive clay; to preserve safety factors that guarantee stability in typical road cross sections such as slope, trench, embankment and mid-slope. The study begins by evaluating geometric recommendations, carrying out the analysis by the Limit Equilibrium Method and by numerical models using the Finite Element Method, supported with the use of application programs in geotechnics. Then a comparative table was made with the safety factors obtained. New geometric dimensions of slopes that guarantee safety were presented for some of the analysis cases.
