Abstract
The generally-adopted soil model in engineering was adopted for analysing the dynamic response of the spherical cavity in nearly saturated elastic soils. The analytic solution in transformed domain was obtained by the method of Lapace transformation, and numerical results were presented through Laplace inversion. The displacements, stresses and pore water pressure were investigated during the response and compared with the elastic case, and some features of the problem were revealed. The model is applicable for engineering practice and provides an effective method for analysing the similar problem about dynamic response of underground structure.
