主　　题：Bearing capacity Eccentric loading Geogrid-reinforcement Model test Rectangular foundation Sand 

摘      要：Laboratory model test results for the ultimate bearing capacity of rectangular surface foundations supported by multi-layered geogrid reinforcement and subjected to eccentric loading have been presented. Based on the model test results a reduction factor has been developed, which is a function of width-to-length ratio (B/L), eccentricity ratio (e/B), and reinforcement depth ratio (d/B) of the foundation. The reduction factor can be used to estimate the ultimate bearing capacity of an eccentrically loaded foundation from the ultimate bearing capacity of a vertically loaded foundation.
