Prof. Vasilev is author of computer programs (written in FORTRAN) for 2D and 3D FEM analysis of Earthfill and Rockfill Dams, Concrete Gravity Dams, Tunnels, Caverns, Deep excavations, Mines and other geotechnical structures.
- ATLAS2 - 2D FEM program for elastic analysis of hydro and geotechnical facilities;
- ATLAS3D - 3D FEM program for elastic-plastic analysis of hydro and geotechnical facilities;
- BACKAN - Program for Back Analysis of measured displacements in tunnels, based on FEM;
- GRADEX - Program for static and dynamic analysis of concrete gravity dams, based on a simplified procedure;
- BEMA – Program for calculation and analysis of stresses, displacements and local stability coefficient (MOHR –COULOMB and HOEK-BROWN criteria) around underground openings using the boundary element method;
- SPLAN – Program for analysis of the effect of seismic wave propagation on straight, segmented, buried pipelines – axial stresses, displacements and opening-closing of joints between pipes. Copyright in Mexico.
