Abstract
A new class of unconditionally stable staggered implicit-implicit time -stepping algorithms for coupled soil-pore fluid dynamic problems is p resented. The proposed schemes are stabilized with a pressure correcti on method and the staggered procedure introduced earlier by the second author(13) is a simplified case of the new algorithms. The stabilized procedure is efficient in numerical time domain analysis of soil-pore fluid interaction occurring in earthquake and consolidation problems. Several examples of linear and non-linear problems demonstrate the st ability and accuracy of the proposed numerical solution algorithms. (C ) 1998 John Wiley & Sons, Ltd.
