RIDGE PIPE PROOF TESTING UNDER EXCESS OVERFILLS WITH VARYING BACKFILL PARAMETERS: SECTION V (VOLUME 5)--EFFECTIVE DENSITIES CALCULATED FROM INTERPOLATED, MODIFIED, MEASURED NORMAL TRACTIONS

"Effective density" profiles were calculated from normal tractions interpolated between soil stressmeters at the outer periphery of the Cross Canyon, reinforced concrete ulvert. "Effective ddensity" is the hypothetical density of an embankment material required to produce, under hydrostatic conditions, a measured soil stress under the measured overfill at the meter. The normal tractions from which these "densities have been derived have been interpolated between readings of soil stressmeters at the soil-concrete inerface and then modified to produce static equilibrium in a horizontal direction. Static equilibrium in the vertical and rotational directions has been achieved through the use of synthesized tangential tractions. (FHWA)
