As a Geotechnical Engineer at a road construction project, the student must develop thepreliminary sidehill cut design as shown in the image below, considering the different conditioningfactors, verification tests and requirements that he$/$she considered to be associated to ageotechnical work of this nature. As can be seen in the image below, the natural terrain height isof $+11,5$ meters while that at which the road platform will be built on$,$ is of $+3,5$ meters. It is theengineers responsibility to determine the sidehill cut angles with the horizontal line, as well as itsbase width according to his$/$her engineering and design criteria.As it can be observed, the phreatic level is $2$ meters below ground surface level.The terrain parameters are:Clay:E $=35,00$ MPa ; $=0,2$ ; c $=25$ kPa ; $=25$ ; sat $=20$ kN$/$m$3$ ; d $=16$ kN$/$m$3$ ;G $=2,7$ ; e$0=0,7$ ; cu $=$ su $=70$ kPa ;Rock:The rock is Massive and sound; width values are unknownRMR $=90$ ; E $=4500$ MPa ; $=0,2$ ; c $=1,3$ MPa ; $=45$ ; $=24$ kN$/$m$3$
