Analysis of Pipeline Failure Probability Caused by Earthquake Based on the Allowable Strain
The earthquake that happened in WenChuan city, SiChuan province of China on twelfth June 2008 greatly impacted the integrity of the LanChengYu pipeline, which is the only way of providing oil products to SiChuan province. The pipeline designers have paid more attention to the threat of earthquakes since then. This paper reviewed the traditional methods of calculating pipeline failure frequency caused by earthquakes, and pointed out their shortcomings. In addition, a new method was provided. First, researchers should calculate the additional strains of pipe caused by earthquakes which are related to the peak ground acceleration (PGA). The method of additional strains calculation was provided in the Chinese industry standard SY/T 0450. Second, the uncertainty calculation was conducted to get the rule of distribution. Finally, the additional strain was compared to the allowable strain of pipe, and the probability of exceeding is the pipeline failure frequency caused by the earthquake. Further, an example was followed. The parameters needed were listed, and the pipeline failure frequency along the station was illustrated. The result may be useful to pipeline designers.
