✦ Synopsis

Gallavresi, F., 1981

. Ground freezing --the application of the mixed method (brine-liquid nitrogen). Eng. Geol., 18: 361--375.

The paper deals with different ground freezing techniques, i.e., open, closed and mixed systems. The main criteria of choice between the various methods are also defined, and some experiments carried out in Italy between 1972 and 1979 employing the mixed system are outlined. In particular, the work carried out in Naples in 1979 is described where the mixed treatment was used to excavate below the water table for a sewer trunk line of 3.40 m diameter in the city centre and beneath existing buildings.

1979 contract No.4 of the Stadtbahnbau (Metroconstruction) in Duisburg was executed, making successful use of gap freezing. The gap freezing was necessary because the Metro-tunnel is crossed by a groundwater stream (flow velocity up to 15 m/d) and it had to be assured that open cut construction of

A new front-tracking method to compute discontinuous solutions on unstructured finite element meshes is presented. Using an arbitrary Lagrangian-Eulerian formulation, the mesh is continuously adapted by moving the nearest nodes to the interface. Thus, the solution is completely sharp at the interfac
