In this work, a numerical model is calibrated using the force-displacement data of Trautmann et al. (1985). The numerical technique is implemented to study the effects of slope angle on soil-pipeline interaction loading. For this purpose, the pipe is displaced in...

Uplift resistance is a key parameter against upheaval buckling in the design of a buried pipeline. The mobilization of uplift resistance in dense sand is investigated in the present study based on finite-element (FE) analysis. The prepeak hardening, postpeak...

A critical review of the definition of soil springs in the available design guidelines – Part – I: Axial Soil Springs Axial soil resistance plays an important role for pipeline stress analysis or pipeline design against the landslides along the pipelines. There is a...

Geohazards and associated ground movement (e.g. landslides, slow movement of soil in a slope, nearby excavation) or thermal expansion during pipeline operation (e.g. lateral movement of pipe at the side bends) results in relative displacement between the pipe and...

Upheaval buckling is a potentially serious problem which can be encountered during the operation of buried oil and gas pipelines operating at high temperature and pressure. Temperature increase causes axial expansion, and if it is restrained by the axial resistance...
