The design of soil reinforced structures with thin concrete facing panels under railways.

The systems of polymeric reinforced soil walls with thin concrete facing panels have been well known for a few decades as a very good alternative to conventional gravity concrete walls. These systems were developed due to big demand from construction point of view, searching for ways how to reduce the cost of existing gravity retaining walls made of concrete and also to speed up the time con-struction. From designer point of view there was a need to tackle geotechnical problems as big size of the structure, differential settlements, earthquake loading, etc. The article talks about the invention and first tests of these structures, about design methods, system components and also about the references.
