| 中文摘要 | Centrifugal experiments were carried out to investigate the stratum instability caused by the dissociation of gas hydrate. First gas hydrate-bearing sample was synthesized using biological anaerobic fermentation method. The silty sand was taken as the skeleton. Then four centrifugal experiments were carried out to study the responses of stratum to the dissociation of the gas hydrate. The characteristics of stratum slide and pore pressure variation and displacement were observed. It is shown that the produced gas can cause the increase of pore pressure and slope slide towards the toe during and after dissociation of gas hydrate. The failure occurs first at the toe of the sample and slides downwards along an arc sliding face. Cracks form at the top of the slope. The slope angle becomes smaller and smaller. This work is beneficial to the further study on the instability conditions of stratum due to the dissociation of gas hydrate. |
