Influence Study of Different Site Type on Seismic Performance of Pipeline with Defects

Abstract:

With the further study on the exploration and development of oil fields,some oil fields have gone into the later period for developing gradually. The problems of oil pipeline are more and more prominent. Earthquakes have occurred frequently in recent years. So it is particularly important to study on the seismic performance of corrosive pipeline. Due to the length of pipeline, the geological condition is more complicated, the same pipeline across the site category may have a big distinction. The software of ANSYS was used in this paper to study pipelines with corrosion defects in different site types. The seismic response were calculated, thus various types of site conditions of the velocity, displacement and acceleration time-history response were obtained, and the results were compared and analyzed.
