The effect of heavy-duty vehicle crossings on the state of stress of buried pipelines
Original language description
The aim of this article is to quantify the loads exerted by heavy‐duty vehicles when crossing over buried pipeline. This problem arises in connection to the question pertaining to the use of protective sleeves (casings) applied to gas pipelines in regions with increased demands on pipeline operation safety. An experiment was conducted on a test pipe section made from L360NE pipeline steel equipped with strain gauges along the pipe perimeter, measuring strains in the axial and circumferential directions. Strain measurements were taken after back‐filling the pipe trench, then during vehicle crossings over the empty pipe, and again after pressurizing the test pipe with air. Strainbased hoop stresses at the surface of the empty test pipe were found to exceed 30 MPa after backfilling the trench and increased to more than 40 MPa during the vehicle crossings. Similarly, axial stresses reached extremes of around 17 MPa in compression and 12 MPa in tension. Applying internal air pressure to the test pipe resulted in a reduced net effect on both the hoop and axial stresses.
