Abstract

Long-term disposal of high-level radioactive wastes in subseabed sediments requires that the sediments constitute the principal barrier to the release of radionuclides over very long times. In this chapter the development of the components for mathematical modelling of creep deformations of marine sediments is presented. This development includes formulation of the conservation equations and constitutive equations tha describe coupled movement and heating of the fully saturated porous sediments. Numerical methods for solving the system of governing equations for complicated two-dimensional geometrics are discussed, and the program of laboratory tests for understanding the mechanical behavior of the ocean sediments is presented.
