Description | Macstars 2000 checks the stability of reinforced soil slopes. It carries out a global stability analysis of a reinforced or un-reinforced slope by using the limit equilibrium method. It can be conducted to check the stability of a non-reinforced slope, prior to considering the reinforcements. The internal stability check allows the user to determine the design of the retaining structure, that is the reinforcing units required (type, spacing between reinforcing unit, length). According to this type of stability analysis the surfaces of potential sliding originate from the toe of the reinforcing structure and, passing through the reinforcement, terminates uphill. The analysis of the retaining or reinforcing structure is considered as a monolithic wall consisting of blocks, which form the retaining structure, itself. The stability check of the structure as a retaining wall consists of the three steps: check against overturning, check against sliding, check against foundation bearing capacity. The reinforcing units are structural elements, which behave as follows: The reinforcing units are resistant against tensile stress. The tensile stress within the reinforcing units can develop due to the adherence between the reinforcing unit and other materials located immediately above and below it. The reinforcing units provide a stabilising force in the area where they intercept a sliding surface, that is the area of the slope in which develops the shear stress, which induces a deformation or extension of the reinforcing unit. As the deformation increases, the strength provided by the reinforcing unit increases as well until it reaches a maximum value which, in relation to the geometry of the considered problem, can be: the reinforcement unit tensile resistence, the pull-out resistence along the anchorage area or the pull-out resistence within the unstable soil portion. In order to consider both common simplified methods and more complex realistic reinforcement behaviour, two analytical models are provided by the software: a rigid model or the deformative model. |
