Strength and deformation characteristics of geocell reinforced soil were studied in a triaxial test. Factors that affected strength and their variation pattern were investigated under different reinforcement conditions. With the same amount of reinforcement, choice of reasonable and economical reinforcement forms was analyzed. The following results are obtained. Strength and anti-deformation capacity of the soil are clearly intensified with reinforcement. Strength is far more improved by increasing the height of geocell than reducing the node spacing when the confining pressure is constant. With the same amount of reinforcement, using large cell height and low reinforced layers is more reasonable. Analysis of the reinforcement effect coefficient and strength shows that the coefficient is reduced with the increasing of confining pressure. Cohesive strength and angle of internal friction of the soil are improved by geocell reinforcement. The improvement of cohesive strength is more significant.
