Energy pipelines are constructed to transverse through different geological terrains. Sometime, they have to be buried at shallow depths in moving slopes, and therefore can be subjected to long-term ground movements. Permanent ground deformations along part of the pipeline length can cause pipe rupture. Thus, the effect of permanent ground deformations on buried pipelines can be critical for their integrity and safety. Understanding this effect is important for pipeline designers, which allows the engineers to continually assess the operation pipeline performance and make decision on necessary remediation. The success of such an endeavour hinges on the accurate knowledge of the pipeline-soil interaction in creeping soils.

能源管道的建设是为了穿越不同的地质地形。有时，它们必须埋在移动斜坡的浅处，因此可能会受到长期的地面运动。沿着部分管道长度的永久性地面变形可能导致管道破裂。因此，永久地面变形对埋地管道的影响对于其完整性和安全性至关重要。了解这种影响对于管道设计人员来说非常重要，这使得工程师能够不断评估运营管道的性能并做出必要的补救决策。这种努力的成功取决于蠕变土壤中管道-土壤相互作用的准确知识。
