Analysis On Vertical Bearing Capacity Mechanism Of Rock Socketed Pile Based On Object-Oriented Finite Element

Rock socketed pile, which is extensively used in the filed of civil engineering,is an important foundation pattern of buildings,especially high and large ones.The researches on rock socketed pile have been being paid close attention to by academic and engineering circles. Though a lot of achievements in the field have been obtained in recent years,many problems remain unsolved for it's complex nature. Many works in the field are in wait to do.Combination of the finite element method and Object-Oriented programming method has become a tendency.On the basis of related literature at home and abroad, study a part of the loading mechanics of rock socketed pile by that tow methods. Firstly,Using 3D 20-node iso-parameter and 3D 16-node interface element, a coupled non-linear numerical approach for the rock-pile system is set up. And then ,the Object-Oriented programming of finite element software RSPA(Rock Socketed Pile Analysis) is developed with Visual C++6.0.As a programme of finite element, RSPA has a lot of pre and post processing function,such as element display, Deformation display and so on. Hoping that the design would provided a basic platform for further research and developing.The character of a test pile is is analyzed. Some loading mechanics of rock socketed pile is also analyzed. The results show that the coupled model is correct and feasible,and the programme result is also satisfying.
