The interaction between fluids and soil is important to a wide range of geotechnical problems. Especially when considering high velocity impacts, such as jet grouting, the interaction between both phases is quite complex, due to the dynamic and turbulent processes occurring. This paper describes a series of experiments concerning high velocity injection into soil, which were conducted in 2005. The experiments are used as a base for the numerical modeling of the process, for which the smoothed particle hydrodynamics (SPH) was applied. SPH is a meshfree method, which was originally employed in the late 1970's for astrophysical calculations. Nowadays, it is being used in a vast range of research domains including fluid and solid mechanics, hydrodynamics and also coastal and geotechnical engineering. SPH uses particles to describe materials in Lagrangian point of view. It is able to deal with large deformations and dynamic processes. Our goal is to provide an innovative application of SPH for the simulation of the interaction between water and soil in the framework of multiphase models. The analysis is supposed to give information on the penetrations process of a high velocity water jet into the soil as well as the penetration depth and the mechanism of soil liquefaction during jet grouting. © 2015 Taylor & Francis Group.
