文摘

Good agreement between the simulations and experiments was found. High coefficients of determination (r2) of 0.96 for the DB and 0.94 for the MCAS. Exp. outcomes show big diff. between Direct Burial and Conduction Augmentation System. Reduced interface soil temperatures resulting in reduced moisture migration. Flexible membrane conforms to a square cornered excavated trench.
