Testing of Subsoil Support in Physical Model of Piled Embankment

Piled embankment is a type of soil structure that offers convenient technical and cost effective solution for the construction of transport lines in situations when soft soils are present, groundwater is near to surface, or there is an organic unbearable soil profile of significant depth. Other reasons for using pile support for embankment is that total replacement of soft soil is not a cost effective solution or that any other ground improvement techniques are not efficient enough. The article describes continuation of research on pile embankment structure design and its verification by a physical model. Partial support of subsoil and load transfer can be considered in piled embankment structure at some cases of subsoil type. Partial support means that the calculated tensile forces induced in reinforcement on pile heads are lower compared to the case of a very soft subsoil (without subsoil support). After a series of tests of physical models of piled embankments without subsoil support, new models with subsoil support have been prepared. There are many possibilities of simulating soft subsoil, the authors' team decided to use mattress foam which has a non-linear stiffness and this material is convenient for the installation. A foam type was selected to simulate partial soil support for which basic parameters were determined for further research.
