| Abstract: |
| With the rapid development of offshore oil and gas fields， the length of submarine pipelines in China is over 6 000 km. In recent years， the stability and security of the submarine pipeline works have been attracting more and more attention of experts and scholars because the accidents take place frequently. The interaction between the submarine pipelines and seabed is the main part in pipeline stability research. On the basis of literature reading， the current status of the experimental research on the interaction between the seabed and the submarine pipelines has been analized， including the types of mechanical loading tests， flume model tests， and centrifuge model tests， as well as the status of theoretical studies， including analysis methods and numerical methods. Finally， the problems concerning the interaction between the submarine pipeline and seabed that need to be further studied are expounded. The analysis results show that the establishment of a constitutive model is an important approach to the study of the interaction among wave, seabed, and pipelines and the stability of the pipelines in the future. |
