FIELD MEASUREMENTS OF EARTH PRESSURE ON A CANTILEVER RETAINING WALL

Field observations of the performance of an 11-ft (3.4-m) high cantilever wall on clay soil retaining a highway embankment in Houston, Texas were obtained. Measurements of wall translation and tilt, lateral earth pressure on the back face and bearing pressure on the footing were made periodically throughout a one-year period. Data acquisition began immediately after wall construction; data were obtained before, during and after placement of the select sand backfill. Measured lateral and bearing pressures were compared with calculated values obtained by published analytical methods, including the well-known Rankine and Coulomb theories of lateral earth pressure. Measured lateral pressures were integrated to obtain the resultant force on the wall. The resultant force was also computed by Culmann's graphical method for comparison with the value obtained by integration. Surcharge effects were studied by comparing the pressures and forces acting on the wall before and after placement of clay above the select sand backfill. (FHWA)
