Abstract
Modeling and calculations of the reinforced soil displacements are a current problem in engineering geology and geotechnical investments. One of the forms of soil reinforcement is the use of geocell systems. Geosynthetics increase the strength of weak subgrade by insertion stiffness for tension and extending the durability of geotechnical structures. Geocell systems are often used in transport infrastructure, for example for reinforcing the subgrade of railway lines. This paper presents the results of finite element analysis of deformation of a subgrade reinforced by geocell-soil composite. As a constitutive model of the railway structure and the subgrade, an elastic model was used. The nonlinear contact conditions between the geosynthetic and the granular soil were considered. In the structural analyzes the finite element method (FEM) and the submodeling technique were used. Calculations were performed for three variants of the reinforced subgrade. Numerical analysis used the Newton-Raphson iterative method. The results of the analyzes showed that the resistance of the system to deformations increases with the reduction of the cell size.
