Abstract

Resistance to pipeline motions in cohesive soils is shown to change with time. The following time effects are distinguished: aging of disturbed soil, duration of constant loading on the pipeline (consolidation time) and rate of external loading. Theoretical treatment of the two latter of these effects is compared with experimental results available in the literature. These experiments confirm the increase of the soil resistance with increasing consolidation time as shown by the theory. They are, however, insufficient to demonstrate the effect of loading rate set forth by the theoretical considerations herein.
