Abstract


A large number of land reclamation , coastal cities , new design requirements for building foundations . Different strata and ground-based reclamation strata , stratigraphic consolidation is not completed , the settlement difficult to control , ground treatment using vibro gravel pile composite foundation of economic , security and effective foundation reinforcement to achieve the engineering foundation design requirements . Firstly collect gravel pile vibro understanding of domestic and vibro gravel pile Research . And vibro principle gravel pile composite foundation in foundation reinforcement learning research , design and testing . Understand its process into a pile in the form , the failure mechanism of processing works to understand to improve composite foundation settlement and differential settlement and enhance the foundation bearing capacity and stability calculations . And its ultimate bearing capacity calculation principle . Bearing capacity , settlement and consolidation principle in the design process . Vibro gravel pile composite foundation testing and construction quality evaluation . Based on the above principle and formula provide a theoretical basis for the design engineering examples and numerical analysis . Papers rely to carry out renovation project for the relocation of the eastern region of Dalian Port vibro gravel pile composite foundation technology research in complex waterfront reclamation under reservoir conditions . The paper focuses on the Gravel Pile Composite Foundation in coastal reclamation formation history of the development of the gravel pile , vibro vibro vibro replacement stone column reinforced foundation works , piling conditions . Waterfront strata reinforcement vibro replacement stone column design and detection methods , vibro replacement stone column test pile and the experimental data , the numerical analysis , provides the basis for the design of vibro replacement stone column . Finally, the author of the vibro gravel pile formation in complex waterfront reclamation summarize , pointed out some problems in the specific design and engineering numerical analysis , and similar work in the future to make some suggestions .
