Abstract: Considering engineering practice, the viscoelastic two-phase model of soils is adopted to analyze the transient dynamic response of the spherical cavity in nearly saturated viscoelastic soils. The analytic solution in transformed domain is got by the method of Laplace transformation; and numerical results are presented through inverse Laplace transformation. The displacement, stresses and pore water pressure are investigated during the response and compared with the elastic case; and some features of the problem are revealed. The study is reasonable for engineering practice and provides an effective method for analysing the similar problem about dynamic response of underground structure.

Key words: nearly saturated soils, viscoelasticity, spherical cavity, dynamic response
