Buried oil pipelines can traverse hundreds of kilometers of terrain with varied environmental and geotechnical conditions, such as earthquake prone areas. These areas experience ground subsidence, will lead to pipeline being suspended, the suspended segment of pipeline may result in pipeline rupture. Suspended oil pipeline stress safety usually has two contributing factors: the length of suspended segment and water buoyancy. In order to research the influence that the two contributing factors cause on the stress of suspended pipeline, it is needed to analyze suspended pipeline stress using analysis software CAESAR II. Research shows that, the buoyancy of water is more sensitive, and suspension pipe length of oil pipe is relatively small. It is provided with some reference results for pipeline safety management.

Stress concentration of the crossing oil pipeline is the main reason for pipeline failure. Currently, the study on the stress analysis of large excavation crossing river oil pipeline also seldom, in order to ensure the safe operation of the pipeline, it is necessary to do analysis of crossing river oil pipeline stress distribution under operating conditions. We do the numerical simulation of the a certain oil pipeline with large excavation method using stress analysis software CAESAR II, come to the distribution of the pipeline, and check whether it can meet the strength requirements or not. Through the engineering case study, we draw that the maximum stress generated at saddle weight under the operating conditions, it means that the saddle weight location is the dangerous section of the crossing river pipeline. Analyze and compare primary stress and secondary stress can come to that temperature difference is the main factor which generates stress in oil pipeline, while the impact of internal pressure is less.
