The Behavior Estimation of the Soil Constructions at Transport Infrastructure with Its Reinforcement by Man-made Materials with Using of Physical Modelling and Testing

Mechanical stabilized earth walls with reinforcing of the man-made materials are widely applied in Russia on the railway and highway track infrastructure for the last ten years. During last years it is the transport infrastructure in Sankt-Petersburg, Moscow and Sochi regions. This study was provided for better understanding of the behavior of soil constructions at transport infrastructure and its separate elements using some methods: historical technical evolution analysis, laboratory testing and physical modeling on the centrifuge. Friction coefficient between a reinforcing element and a fill soil takes direct part in internal stability analysis of construction. Its value depends both on type of a reinforcing material, and from filler (sand, gravel and other soil types). The special device was designed for the tests and definition of factor of an internal friction between the geogrid and soil. Some experiments have been conducted for the reinforcing element.
