Kurzfassung englisch:
In the present paper the static load plate test and dynamic load plate test with the Light Falling Weight Device (LFWD), and heavy tamping are evaluated by means of extensive numerical studies utilizing the Boundary Element Method. The compacted soil medium is modeled either as a horizontal semi-infinite layer with constant thickness and an underlying halfspace (in the case of the load plate tests) or as a homogeneous halfspace (in the case of heavy tamping). The dynamic load plate test is simulated by means of the sub-structure technique (substructure 1: falling weight and spring-damper element, substructure 2:load plate and elastic soil medium) separately and then coupling them iteratively. The static load plate test is evaluated using substructure 2, while for the simulation of heavy tamping the model is modified in order to consider a vari-able penetration depth of the falling weight. The results of the presented study cover a wide range of soil characteristics considering various material properties and layer thicknesses and/or penetration depths.
