Geosynthetic Reinforcement in the Mitigation of Pipeline Flotation - Reinforced Soil Engineering: Advances in Research and Practice - page 245

9 CONCLUSION
The experimental study of pipe flotation has been conducted using a 110-cm-
diameter pipe. It was shown that the geogrid can be used effectively to reduce
flotation of pipelines with the gravels and soil cement acting as backfill material.
An integrated body was obtained when the geogrid was placed above the
pipeline. The soil above the geogrid contributed additional overburden weight.
The geosynthetic functioned as not only tensile reinforcement, but its bending
stiffness also played a role.
