AN ASSESSMENT, USING THREE FIELD STUDIES, OF THE THEORETICAL CONCEPT OF THE EFFICIENCY OF DRAINAGE LAYERS IN AN EMBANKMENT

The efficiency of drainage layers in an embaknment has been defined in terms of the pore-pressure dissipation (Gibson and Shefford, 1968). In order to relate this to field experience, three embankments have been studied. In each case, the pore-water pressure that might be expected to develop in the absence of drainage was calculated. This was then compared with the measured pore-pressure, to obtain an estimate of the degree of dissipation due to the drainage system. By relating this to the calculated efficiency, the theoretical concept can be assessed in comparison with observed behavior. /Author/TRRL/
