UPLIFT BEHAVIOUR OF STRATA-GRID ANCHORED PIPELINES EMBEDDED IN GRANULAR SOILS

This paper presents the results of a program of experimental research which was conducted to establish the enhancement of uplift capacity of buried pipelines, which could be derived from the utilization of a woven synthetic geogrid known as strata-grids. The strata-grid is placed immediately above the buried pipeline in an inclined configuration, to derive the desirable anchorage characteristics. Experiments were conducted on strata-grid anchored pipelines which were embedded in either sand backfill or crushed granular 'A'-type backfill. It is observed that the incorporation of strata-grids results in a significant increase in the uplift capacity and that the increased capacity is sustained for large uplift movements of the buried pipeline.
