Sediment mechanical response due to emplacement of a waste canister
Date of Original Version
Preliminary studies have been conducted to de-termine the interaction between a waste canister and seabed sediment during and after emplacement. Empirical and approximate methods for determining the depth reached by a free-fall pen-etrator indicate that a boosted penetrator emplacement may be necessary. Hole closure is necessary, but has not been verified because calculations and laboratory experiments show sensitivity to boundary conditions that control the degree of dynamic hole closure. Laboratory studies show that closure will take place by creep deformation, but closure times in seabed environments are uncertain. For assumed thermomechanical properties of sediments, it is shown that a heat-generating waste canister will probably not move a significant distance during the heat-generation period. © 1984 Taylor & Francis Group, LLC.
