| Gas hydrate is a new and huge reserve energy resource on the earth with high efficient and pure characteristics. It usually exists in rock, sand, clay and some other types of sediment. The research on mechanical properties of gas hydrate sediment is one of the most important and popular topic related to the stability analysis of foundation in gas hydrate sediment stratum and the gas hydrate exploration estimation. Firstly, the apparatus of synthesis and dissociation, the technique of physical property measurement and the apparatus of mechanical property measurement about gas hydrate sediment testing in laboratory are introduced in this paper. Then, the achievements of integrative apparatus and research on the mechanical properties of gas hydrate sediment are presented with typical abroad and domestic devices. Finally, the problems existing in laboratory test apparatus, measurement technique and laboratory research are pointed out, and the emphasis and tendency in the future research on the apparatus and mechanical properties are suggested. |
