Mitigation systems for the uplift of buried pipelines in liquefiable soils under repeated shaking through model tests

Uplift resistance of buried submarine pipelines: comparison between centrifuge modelling and full-scale tests

A buried pipeline can buckle upwards if there is not enough resistance to movement. Both the uplift resistance (the maximum force per unit length) and the mobilisaion distance (the distance the pipeline has move before the maximum force is reached) are important in design. Tests on pipes in several soils were carried out at 1 g at full scale and in a centrifuge at 10 g and 1/10 scale. A compari...
