The use of trial embankment observations in the construction control of roadway embankments on soft soil

Measurements from an instrumented trial embankment were used to develop calibrated stability and settlement analysis models, for the behaviour prediction of high roadway embankments on soft soil. The analysis models were based on the relatively unsophisticated classical theories. The effective stress stability model was used to prepare a stability monitoring diagram, which, in conjunction with very simple pore pressure and settlement measurements, was used to control the rate of filling the roadway embankments. The settlement model provided realistic estimates of settlement behaviour, and showed that surcharging was required to bring consolidation times within the available construction period. The embankments were successfully constructed under stability control without need of stabilisation measures, and primary consolidation effectively completed within the available construction period (a).
