Paper Number: OTC-31976-MS
... redistribution within the rock mass and arching over the pipe crown where the rock becomes partially self-supported. This results in loss of active load on the flowline, thereby impacting the static shear resistance (‘friction’) at both the flowline-soil and flowline-rock interfaces. The simple schematic...
