Abstract
As the stress is one of the main factors affecting the safe operation of the pipeline in the gas pipeline tunnel crossing project, in order to ensure the safe operation of the pipeline, it is necessary to research the stress conditions of the gas pipelines in the deviated well. In this study, we discuss on these two aspects of the gas pipelines in the deviated well: the necessity of adding buttresses and the distance between buttresses. We do the numerical simulation of China Shaanxi-Beijing III gas pipeline in the Eighth Fort Yellow River tunnel areas using stress analysis software CAESAR II; exploring its secure and economical buttresses distance. Our research shows that the pipeline can be safely run after adding buttresses and it is more reasonable to set buttresses distance of 20 m for the numerical example. Our research provides a reference for the design of the buttresses distance of gas pipelines in the deviated well and has some engineering value.
