WebMay 3, 2024 · The seismic design of tunnels is based on two approaches: (1) soil-structure interaction and (2) free field approach. In the first approach, the soil shear strains are affected by the deformation of the nearby underground structures and will conform to the structure strains. WebSeismic. Several different seismic methods are used in geophysical surveys. Seismic refraction uses P- and S-wave energy to map vertical and lateral subsurface changes. Multi-channel Analysis of Surface Waves (MASW) is a nondestructive seismic method used to evaluate the shear-wave velocity distribution and arrangement of overburden soil ...
