STRENGTH OF FROZEN SAND CONTAINING TETRAHYDROFURAN HYDRATE

Cylindrical samples of frozen sand containing tetrahydrofuran hydrate were tested under uniaxial compression at 267 K and strain rates between 0.000001/s and 0.001/s. In the low strain rate region the compressive strength of the samples was higher than that of frozen sand containing ice. For example, at 267 K and a strain rate of 0.000001/s the peak stress for the frozen sand containing hydrate was about 16 MPa, whereas the corresponding value for the frozen sand containing ice was only 10.5 MPa. The strain rate dependence of stress for the frozen sand containing hydrate was much smaller than that of frozen sand containing ice, so that at higher strain rates the compressive strengths of the two materials become almost the same. Cold regions, such as Siberia, Alaska, and the Northwest Territories of Canada, contain hydrate deposits within the soil mass, which, in view of the problems experienced during drilling and excavations, are a possible source of energy. Because of this, the physical and mechanical properties of hydrates and frozen soils containing hydrates is being investigated.
