| Dock is built in a shipyard inside, used to build the ship hydraulic structures. Along withour country’s shipping industry 12·5 development plan of release, Chinese shipbuildingindustry system will be more perfect, the industrial structure tend to be more reasonable, tomeet the shipbuilding industry of booming development requirements, it’s necessary toincrease the dock engineering construction force. In recent years, with the dock, dock portbuilding such as the increasing of, don’t deal with the direct use of natural foundation of goodbut less and less, so there will be a large dock and similar engineering building in the softfoundation. However, in its complex foundation or weak foundation, how to be better able todesign a reasonable both safety and economic dock motherboard, become the researchers thekey point is to focus on one of the subject. Taking a dock engineering as an example, in softfoundation of the dock on the floor below piling, to enhance the bottom bearing ability, and itsas the pile raft foundation. But the pile soil mechanism, deformation characteristics of thestudy also less, engineering and technical personnel to the structure and soil interactioncharacteristics also don’t know enough about, so need to be deeply understand its mechanism,analyzes the stress and deformation characteristics, for related engineering design to providethe reference.This article in view of the docks in soft foundation floor structure on the needs of thedevelopment, the finite element analysis software ANSYS in Hollywood have a ship, emptyempty dock without ship and in Hollywood, three water under different working conditions,the deformation characteristics and floor docks of piles and soil in the interaction between thecarries on the discussion, consider pile soil under the joint action of the contact between thethree. Through the analysis of earth pressure that empty without boat dock, board dock wallsof transfer by pressure and weight of itself, the internal forces and deformations smaller plate,pile, the board was basically the same earth pressure value; Empty in the dock, floor in thecentral bigger bending moment, board and pile happens the uneven settlement, pressure valuehas larger changes, and the central large; Under the action of water in Hollywood, floorhappen relatively uniform settlement, pile, the pressure plate were significantly increased.Using the finite element method to calculate the bottom of the normal stress dock room withthe elastic foundation beam method of the calculation results, the two algorithm’s agreementwith the results of the degree is higher, this also showed the finite element software ANSYSin engineering in the calculation of the reliability. Pile in Hollywood and soil lateral bycommon, and no sufficient study effect, this kind of structure of the mechanical characteristics have not yet fully understood, its design and no mature standard to be followed. Therefore,the research of this kind of structure with practical engineering application value, but also forthe project design of this experience. |
