In the paper interaction of jet grouting columns with the subsoil is presented ([2], [3], [11], [12]). The essence of interaction considered is the influence of soil properties on column's load bearing capacity and settlement ([3], [6]÷[8]). Bearing capacity and settlement tests for jet grouting columns were carried out in Bojszowy Nowe (Poland). In this paper analysis of the results of load and uplift tests for jet grouting columns and the results of the strength parameters for jet grouting material are presented.

Polem dociekań i badań przedstawianych w artykule jest problematyka wzajemnego mechanicznego oddziaływania kolumn wykonywanych techniką iniekcji strumieniowej i podłoża gruntowego ([2], [3], [11], [12]). Istotą tej współpracy jest wpływ właściwości gruntu na nośność i osiadanie kolumn ([3], [6]÷[8]). Badania nośności i osiadania kolumn iniekcyjnych zostały wykonane na poligonie doświadczalnym w Bojszowach Nowych (Polska). W artykule przedstawiono analizę wyników otrzymanych z próbnych obciążeń na wciskanie i wyciąganie kolumn iniekcyjnych oraz podano parametry wytrzymałościowe tworzywa gruntowo-cementowego badanej kolumny iniekcyjnej.
