| 摘 要： | 给出了地震条件下管土之间约束状态的判断准则，并以此准则对工程实例进行了计算和分析，进一步证实在海底埋设环境下，管土之间的约束进入了塑性状态，超出了现用规范将管土之间假设为弹性约束状态的使用范围。因此，进行海底管线的抗震设计时，必须依据本文提出的准则首先判断土壤和管线之间的约束地震时是否在弹性范围内，超出弹性范围就必须按土壤进入塑性滑移理论进行极限地震应力分析。 |
| 关 键 词： | 海底管道 弹性约束 地震波 管土相互作用 抗震设计 |

| Abstract: | A criterion is developed to predict the constraint state between soil and the pipelines, on which engineering calculations for several subsea pipeline projects from CNOOC are based. The results demonstrate that the elastic constraint range of the soil on the pipeline is quite small and the plastic slippage of the soil takes place soon after the elastic state. It is strongly recommended that the constraint state of the soil on the subsea pipeline shall be determined by the developed criterion before calculating the seismic stress of pipeline. The seismic stress shall be calculated based on the plastic slippage theory if plastic constraint state of the soil is predicted. |
| Keywords: | subsea pipeline elastic constraint seismic wave soil-pipeline interaction seismic design |
