| Abstract: | A systematic overview of the aspects of PHC pipe-piles including mechanic theoretical approaches, testing methods, domestic and foreign research development is presented. Through the study of the stress field of jacked piles, a model of cylinder cavity expansion and Mindlin solution of stress are introduced. Vertical stress, static pressure and ultimate bearing capacity are resolved while considering the effect of earth plug on stress field. In practical applications, the analytical solutions can be used to assess the varying regularity. Compared with on-site measurement results, its reliability and practicability are conformed. |
| Keywords: | PHC pipe-piles effect of earth plug mechanics of jacked piles |
