 note = {The purpose of this study is to understand the soil properties of grounds which contain shallow type gas hydrates. For this purpose, the surveys were conducted in Lake Baikal, Russia from 2005 to 2007, where shallow gas hydrates existed. For the lake-bottom sediments, physical and mechanical properties were tested (on-board and laboratory tests). The tested samples were retrieved from the mud volcano ground which contains the shallow gas hydrates, and reference ground at the same area. From these results, it was found that the gas hydrates distribute in large amounts in the lake-bottom sediments of Lake Baikal, and that form of the gas hydrates are varied. In addition, the reference samples in Lake Baikal have no marked differences in the soil properties of the sediments obtained from other sea-bottom grounds. On the other hands, the strengths of the mud volcano samples were lower than those of the reference samples. It would seem that these results are due to the effect of the disturbance of sedimentary layers by upwelling of gas and water from underground and the pressure release during the sampling.},
