Abstract
Optimization of reinforcement geometry interacting with the soil is important from both technical and economical viewpoints. Varying width along the geosynthetic strip may have a major effect on its performance and can be evaluated by pullout tests. This paper presents pullout behavior of geotextile reinforcements with constant, uniformly and stepped varying widths by performing pullout tests and developing an analytical solution. The analytical method involves the solution of derived governing equations to predict the tensile force and displacement along geosynthetic with varying width. The predicted data from the developed analytical method were validated using laboratory pullout test data, resulting in reasonable agreement. It was found that increasing the width in the front parts of extensible reinforcement having large displacement in pullout tests leads to a greater interaction in reinforced-soil system. Better performance for geotextile with uniformly varying width was obtained compared with that for stepped varying width of reinforcement.
