摘要
The purpose of this paper is to study the dynamic behavior of softground including a porous layer by considering porosity change. Inorder to take the porosity change into account, the concept of thevolume fraction, which has been proposed in continuum mechanics, isintroduced. The constitutive equations presented by Bowen are appliedto the analysis of the porous media. According to Bowen's theory, theporosity is considered as a variable called the volume fraction andhas its own consti- Tutive equation.
