Abstract: The structural integrity of buried pipe is always threatened by explosive loads. To investigate the mechanical response of a buried steel pipe under multiple explosions, pipe–soil interaction models in soil and rock layers ...

Abstract: To provide efficient pigging operation, a stable and moderate speed of the pig is preferred. This paper describes a brake device for controlling the speed of a pig in a gas pipeline. A pigging model of a pig with a brake ...

Abstract: Transportation corridors have backwash-spread effects to their surrounding areas on diverse resources, and this is the main factor in regions’ generation and expansion. This paper defines corridor field potential energy ...

Abstract: Characterized by unmanned excavation and remote controlling, the new pneumatic caisson (NPC) method has advantages in deep excavation such as deep shield tunnel shafts and some underground construction close to the existing ...

Abstract: The long-term integrity of the bentonite buffer is of significant interest in the performance assessment (PA) of geological nuclear waste disposal. This study aims at understanding how the initial bentonite chemical ...
