Study of the geometrical and the geotechnical stability of the concrete lozenges channels

Abstract

Several methods are proposed for improving the slopes stability. We are studying the use of a new technique: concrete lozenges channels. The objective of this technique is to stabilize the slope against water erosion. In addition, it makes it possible to combine both mechanical protection with concrete lozenges channels and protection by plant engineering techniques with plants adapted to the area. The present study is part of the continuation of a parametric study whose purpose was to define the optimal design of concrete lozenges channels. Using the finite element method, the purpose is to study the geotechnical stability of a slope stabilized by said lozenges and to define their constructive arrangements.
