Numerical Simulation of Buckling Behavior of Steel Frame-Reinforced Polyethylene Pipelines Under Reverse Faults with Different Inclination Angles
Buried steel frame-reinforced polyethylene (SRPE) pipelines are vulnerable to bending-compression buckling, sectional distortion, and tensile rupture when crossing reverse faults. Nevertheless, their multi-mode failure mechanisms and strain evaluation frameworks have not been systematically clarified. Given this challe...
