摘要

The significance of the pre-overburden pressure in the calculation of settlement of a highly skewed bridge abutment part of a motorway in Western Sydney on a heavily overconsolidated base is evaluated. The uncertainty linked to the linear-elastic moduli considered in the method of layerwise summation is controlled through calibration against settlement monitoring.
