| Research Abstract |
For examination of the soil properties contained shallow type methane hydrate, various strength tests were conducted for the sediment samples collected from shallow type methane hydrate ground. From these tests, the strengths and suction of the sediments into methane hydrate are lower than other areas sediments. Therefore, it was considered that the sedimentary layers were disturbed by gas and water upwelling from underground and the pressure release during the samples. In addition, it is considered that the anisotropy into the specimen made of low salinity levels were equally high regardless of the condition of K0-consolidation from the tests performed by soil change salinity level in the pore water.
