摘要：The uniaxial compressive tests are conducted on synthetic gas hydrate-bearing sediment samples by using the low-temperature high-pressure triaxial test system. The effects of the temperature, the strain rate and the failure time on the uniaxial compressive strength of hydrate sediment are measured. The results indicate that: (a)The uniaxial compressive strength is sensitive to the change of temperature and increases exponentially as temperature decreases. (b) The uniaxial compressive strength of hydrate sediment changes with the strain rate obviously, and increases with the strain rate increasing following a power function. (c) The uniaxial compressive strength increases with the failure time decreasing following a power function.
