| Along with the world economics high-speed development, the international trade is increasingly frequent, the shipping ships tend to more and more greatly the large scale, and the large-scale deepwater wharf also arises at the historic moment. Platform for retaining walls was one kind of new structure, which appears deep-water long-piled wharf in our country recently. In this structure, the depth of backfill is very big, and the pile-soil interaction as well as the stress-deformation of the structure is very complex. So researching this structure has the vital significance to design, construction, maintenance and promotion. This article takes the Platform of long-piled wharf in some deep-water port as the example, and analyses this structure based on 3-D finite element method.First, this article had carried on the analysis to the commonly used computational method, through comparing each method the good and bad points, explained the 3-D finite element method can manifest the characteristic of the structure well. This article took the 3-D finite element method as the main research technique.Next, this article explained the necessity to analyzing this structure based the simulation analysis technique through comparing the non-simulation result and the actual result.Once more, this article has analyzed the pile body deformation and the pile side earth pressure, and discussed the pile-soil interaction based on 3-D finite element method.Afterwards, this article has analyzed the structure stress, and proposed the revised design in this foundation.Finally, this article has compared the structure stress of the revised design and which of the original design, explained the superiority of the revised design. |
