Karolinka Earth Fill dam was built on the Stanovnice river above the town of Karolinka in the region of Vsetín. Because of leakage on the downstream dam face due to bad compacting of soil during the construction stage, the reservoir was used to a limited level. There were some steps to improve safety which had been developed to reconstruct the dam after extensive surveys in 2005. The major rehabilitation was commenced in period from September 2012 till October 2013, included the remediation of central impervious core in the dam by using the diaphragm wall (I also have worked on) and jet grouting pile from self-hardening cement-bentonite suspension. The article presents three-dimensional modelling of a jet pile construction, by using finite element method which is performed by Plaxis program. It is concluded that real data shows good agreement with the computed result obtained by the FEM analysis.

Keywords: Karolinka dam, jet grouting, Plaxis 3D, water head, displacement, autogenous shrinkage
