Numerical Analysis on the Ground Vibration Isolation of Duxseal

Table 1

Calculation parameters of soil and Duxseal.

	Density (kg/m^3)	Young’s modulus (MPa)	Poisson’s ratio	Damping ratio	Thickness
Topsoil	1800	140.98	0.33	0.05	1
Subsoil	1522	59.04	0.44	0.05	5
Duxseal	1650	8	0.46	0.18–0.0003 × (σmean/0.001)	—

σ_mean is the average effective stress. The relationship curves of G−σ_mean and D−σ_mean are provided by Pak et al. [8].
