Comparisons of Two Approaches for Geotechnical Model Calibration with Scarce Data

Table 6

Comparisons of reinforcement area per unit width for facing design against flexural failures using default and calibrated FHWA simplified facing load models.

Approach	Reinforcement area per unit width, (mm^2/m)
		, sample bias	, MLE bias
Default FHWA	266	730	1135
Cali. FHWA, PDC	212	446	430
Cali. FHWA, RMSE	232	492	447

Assuming log-normal distribution for bias.
