Abstract: 

A series of reduced scale physical tests to investigate oblique load effects, in the lateral-axial plane, on a buried pipe in cohesionless soil were completed with a rigid 46 mm diameter pipe. The pipe was buried at two burial depths, H/D of 2 and 4, and was tests at 5 different angles between 0 degrees (pure axial) and 90 degrees (pure lateral). The shallow pipe modeled a 304mm pipeline and the deeper pipe modeled a 609.5 mm pipeline. Failure surfaces for the yield load and mobilization distances were established and compared with previous physical tests and numerical simulations of oblique loading events. It was found that the results were in line with previous reduced scale tests but closer to the results expected based on the ALA guidelines.
