Earthquake fault zone pipeline construction method and arrangement

摘要

Where a pipeline is to cross an earthquake fault zone, a trench is dug in the earth substantially wider and deeper than the diameter of the pipeline. The pipeline is installed in the trench in a bed of spherical bodies, which thereafter function during an earthquake to partially absorb compression and shear waves, and to disperse forces acting on the pipeline, whereby the effect of such forces on the pipeline is minimized with the result that rupture does not occur.
