Calculation Steps

-->        

           Before begining to design a retaining wall we need to establish the different restraints that we might have in terms of :

• site geometry and initial conditions ;
• the nature of soil(soft, rock or different layers);
• the posibility of  using as much site material as possible;
• for slopes with heights above 1.5m  we need to determine the depth of the water behind the future retaining wall in order to determine the hydrostatic pressure
• nature of soil in front and at the base of the future retaining wall .
