| 摘要： | This study reports on the insitu investigation, site stratigraphy, field monitoring, data reduction and subsequent time domain analysis of soil-structure interaction at St. George Island Causeway Pier 1S and 3S subject to barge impacts. The insitu investigation involved Standard Penetration Testing, Electric Cone Penetration Testing, Dialtometer Testing and Pressuremeter Testing. The insitu testing was used to identify soil stratigraphy, engineering properties (i.e. strength and moduli), as well as axial T-z and lateral P-y nonlinear soil-pile spring behavior. The field instrumentation included soil total stress and pore pressure gages in front and behind the embedded pile cap as well as a fully instrumented (strain gages along length) pile attached too the lead row of the Pier 1S (5X8 layout). |
