A Study Of Vibroflotation Composite Foundation In The Complex Coastal Reclamation Layers

A large number of land reclamation in the coastal cities proposed the new design requirements for the foundation. Different with the land-based layer, The Reclamation layer consolidation is not completed,and the settlement difficult to control. The Vibroflotation used in the foundation treatment can be economic, safe and effective to reinforce the foundation in order to satisfy engineering requirements.At the first, this article collects the information of Vibroflotation Composite Foundation, and understands the research at home and aboard. the principle , design and test of Vibroflotation composite foundation reinforce foundation. In this process, to understand the form of pile, failure mechanism and processing works to improve the composite foundation to understand their function, control of settlement and differential settlement and enhance the bearing capacity and stability calculations. And in order to calculate the bearing capacity Principle. In the design process, we study on the bearing capacity, settlement, and principle of consolidation. Testing and evaluating the construction quality of Vibroflotation Composite Foundation are studied. Based on the above principle and the formula, project in engineering design and provide a theoretical basis for numerical analysis.The paper is based on the transformation Project of the eastern region of Dalian Port and studies its reclamation area to treat the layers, specifically the Vibroflotation Composite Foundation used in the complex coastal reclamation area. This paper focuses on the development history and the application of the Vibroflotation Composite Foundation and focuses on the working mechanism and pile condition of the Vibroflotation Composite Foundation. The design and the common testing program which the Vibroflotation Composite Foundation reinforce foundation are mentioned. Then in this paper, the experimental data of pile test was studied, which used for the design of the Vibroflotation Composite Foundation in future.Finally, the author summarized Vibroflotation Composite Foundation In the Complex Coastal Reclamation Layers, and pointed out that the specific design and numerical analysis of engineering problems, and make some suggestions to similar work in the future.
