摘要	A series of tri-axial compression tests on tetrahydrofuran (THF) sediment samples were performed. Meanwhile, the ultrasonic wave and electromagnetic wave reflection properties were measured with ultrasonic transducer and time domain reflection technology (TDR). It is shown that P-wave, electromagnetic wave and stress-strain behaviors of hydrate sediment are affected by hydrate saturation. The shear strength increases and the stress-strain behaviors are very different when hydrate saturation increases. The physical properties obtained from P-waveforms and TDR data are very good complements for better understanding hydrate sediment samples.
