| Abstract: | Analyzed the pipeline stress situation in the long-sloping area,and derived the math formula of the pipeline length and gradient to down-slide stress.Besides,introduced the stress experiments result of DN100 steel tube and victualic coupling,and provided the maximum permitted push stress under this situation,and advanced the method how to avoid the pipeline to slide downwards under this situation. |
