.... The most common formulas are the Skempton formula and the Terzaghi formula. The above formulas are both based on the shear strength of the soil and the size of the structure, ignoring the effect of time on the adsorption force of the structure. Therefore, they often overestimate the adsorption force...

... to protect pipelines against large deformations. This kind of pre-excavated material usually gets highly remolded and becomes considerably softer than the native seabed soil. The shear strength difference between the backfilling and seabed soil can result in the pipeline-backfill-trench interaction during...

... ABSTRACT Deep-sea sediments have the characteristics of high water content, strong compressibility, low shear strength, and relatively soft. Mining vehicles will experience substantial sinkage when operating on the seabed, and additional compaction resistance and bulldozing resistance...
