Abstract:For long-distance natural gas pipes crossing highway, the changing load of vehicles is the most important and frequently acting-live load on buried pipes, which poses a serious threat to the integrity of the pipe. This study has designed and built a buried pipe stress test experimental system. The experimental system is mainly composed of a sealed pipe, an air compressor, and a stress-strain testing system. In this study, a total of 24 sets of stress test experiments are carried out. The research conclusions a… Show more
