“…Hence, these problems are defined by their geometry: d , w , l , h and t ; by the properties of their regions: poroelastic soil (φ, ρ f , ρ s , µ s , λ s , ξ s , Q, R, ρ a , b) and wall (ρ b , E b , ν b , ξ b ); and by the frequency ω. For elastic soils, the open trench and the simple wall problems have been extensively studied, whereas the open trench-wall system has been rarely studied [34]. In these cases, each problem is easily nondimensionalized to a small set of parameters of general applicability.…”
