The stability analysis study of conventional retaining walls variation design in vertical slope
Journal of Physics, Conference Series
One of the hazards that usually occur in slope is landslide. This disaster can occur due to various factors, such as soil material, load on the slope, and the presence of groundwater. Retaining wall is one of the reinforcements that can be applied in slope. This reinforcement is expected to overcome the landslide hazard that can possible to occur. For the conventional retaining wall in kind of gravity wall, the weight of structure influences the stability to retain the slope. Moreover, the
... Moreover, the weight of retaining wall is determined by its dimension. The assumptions of retaining wall dimension is determined by trial and error. If retaining wall is not enough to bear the load, the dimension of the retaining wall must be changed. In this study, analysing conventional gravity type of retaining walls with several variation designs in 3 meters vertical slope. As the limitation of this study, there are two layers cohesive soil behind the retaining wall. The retaining wall only relies on the weight of the structure as the basis of its design. Therefore, the relation between weight of retaining wall with stability of the structure itself can be known. Thus, the design of the suitable retaining wall that is used on the vertical slope in this study can be obtained. Results show that the greater the retaining wall, the value of the safety factor will increase. The design of the retaining wall with sloping wall on the front of the retaining wall gives greater safety factor than the design of the retaining wall with the slender shape.
