Design of geosynthetic reinforced walls and slops by terram program

Abstract EN

This research deals with the design of geosynthetic reinforced walls and slopes subjected to series of static compressive loading tests by the present TERRAM program.

The objectives of this study are suggesting an optimum geometry of reinforcement placement to lessen the width of the side slope of slopes.

The effects of the following variables were taken into account : the angles of slope, wall or slope height, surcharge, strength parameters (cohesion and friction angle) and unit weight for all soils involved in the problem (fill, natural soil and foundation soil), friction angle for reinforcement-soil and fill-foundation interfaces, as well as internal and external factors of safety are calculated for different distributions of tensile force in the reinforcement layers according to the different arrangements of reinforcement layers in terms of number, length, and spacing.
