| Abstract: | Common methods for calculating bearing capacity of reinforced swelling soil foundation are reviewed and analyzed in this paper with consideration of loading characteristics, reinforcing mechanism and failure mode in highways. Based on the review and analysis, the Binquet J. Lee K.L. method, Yamanouch and Gotoh method, and deep foundation effect method are selected for domestic applications. Results of the study provide important guidelines for the design of reinforced swelling soil foundation for highways. |
