Computation And Analysis On Hanging Box Of High Pile CAP With Integrated Finite Element Method

With the development of construction technology and mechanic about deepwater foundation, hanging box weir had being applied widely for construction of high pile cap. In this thesis, on the basis of the existing construction and design data in the world, as an example of Daliao River Bridge, which is the second deepwarter bridge above Daliao River, the auther makes a review and summary of hanging box construction method, introduces design and construction process of the hanging box of Daliao River Bridge in detail. The paper introduces large-scale FEM software, ALGOR, by which the auther can build model of hanging box of high pile cap, and simulates accurately three loadcases, which include loadcase behind enclosed concrete, loadcase behind empty water in hanging box, and loadcase behind high pile cap construction. The auther calculates tensor and displacement of hanging box weir when loads exert panels, supports, suspenders, top beams, base beams of hanging box weir. At the same time the auther carrys out the stability analysis, besides, educes calculational and analytical data, which are tally with construction result in the main. Study in the thesis indicates integrated finite element method is significant for the calculation of construction structure in the reality.
