Study And Application For Spacial Finite Element Mothod Of Piling Wharf Designing

Piling wharf is one of the three most universal kinds of wharves, and it is usedwidely in China, especially in those areas with weak foundation. Due to manyexcellencies, like constructing quickly, bigger spans, less quantity of materials, aswell as high efficiency for assembling, those with upside structures composed bybeams and plates are more widely used instead of other sub-kinds of piling wharves.Piling wharf is a complete spacial structure. Theoretically, it should be analyzed andcalculated as a holistic structure. But in fact, it is very complex and difficult foranalyzing and calculating. Therefore, it is important to assure the design economicaland credible to simulate the loading conditions and stress states.Firstly, this thesis discusses the general methods to analyze and calculate thestructure of piling wharves. At the same time, it also states and discusses theapplication and problems of the Finite Element Method (FEM) in the field ofstructural analysis, calculations and design.Aiming to the wharf design of a 200,000DWT berth in Yingkou Port isintroduced in this thesis, the spacial finite element method was used in the numericalmodel analysis and designing calculation, validated by a related physical modelexperimentation. Within the numerical model analysis, some models were discussedand compared. By comparing with the result of physical model experimentation, theblock element was recomnended in deisgn for simulating rigid beams and pilecaps,rather than the beam element commonly used. The results of this kind of numericalmodel analysis are different from those of accustomed methods, but in consistent withthose of physical model experimentation. This is very important and helpful to adjustthe structure design.The model of spacial finite element analysis recommended and the conclusionof this thesis could be taken as a reference for analogous projects with rigid beams,plates, and pilecaps. The problems indicated in this thesis also could be taken as areference for the updating of related codes and standards.
