Numerical analyses such as the Finite Element Method (FEM) and the Boundary Element Method (BEM) are powerful tools for analyzing the mechanical behaviour of structures. In the field of geotechnical engineering, however, it is extremely difficult to quantitatively determine the mechanical properties of soils/rocks, initial stress, underground water level, permeability, etc., which are required as input data for the analyses. This difficulty is mainly due to the complex and non-homogeneous geological conditions of the ground. It is not surprising that material properties vary from place to place, although soil/rock formations seem to be identical. It is not uncommon, therefore, for the real behaviour of structures such as tunnels, underground caverns and cut slopes to differ from the predicted ones, even after a careful investigation has been made.
