WebbA method of calculating the wave field of horizontally layered soils is presented. It combines numerical integration in the wavenumber domain with the matrix method for layered soils in the most simple way. The three-dimensional problem of a harmonic horizontal or vertical point load acting on the surface of the soil is investigated. WebbPropagation models can study the runout and deposit of potential flow-like landslides only if a reliable estimate of the shape and size of the volumes involved in the phenomenon is available. This aspect becomes critical when a collapse has not yet occurred and the estimation of the unstable volume is not uniquely predictable. This work proposes a …
