| The
removal of soil cores from sampling tubes must be accomplished with the
minimum of disturbance, particularly when small specimens have to be prepared
from a large sample in order to carry out strength tests. Large extrusion
forces, used indiscriminately, will compress soil resulting in false valves
of shear strength and consolidation. |
