Research On System Of Design And Calculation Of Highway Bridge Pile Foundation

The most disadvantageous load calculation, internal force calculation and reinforceme -nt calculation of pile foundation is more complex as well as checking computation , the whole process of design and calculation of pile foundation is a heavy workload, When using manual calculation, it is easy to make mistakes, The design cycle of pile foundation is long and it is difficult to achieve satisfactory results. With the development of analysis methods and calculation methods of pile foundation, using computer to do pile foundation engineering design is imperative. Currently, Recently, all kinds of design and optimization design even intelligent design of computer system of structure continually produces, many of whom have phased to practical. However, because of the complexity of the pile soil system, there are many difficulties to developping a pile foundation of computer design system that is fully functional and can be widely applicable to general engineering conditions.The thesis' theory is based on the code for design of ground base and foundation of highway bridges and culverts (JTG D63-2007), the general code for design of highway bridges and culverts (JTG D60-2004) and the code for design of highway reinforced concrete and prestressed concrete bridges and culverts (JTG D62-2004), using the MFC (Microsoft Foundation Class) Class library of VC++, I developed the program of "Design and Calculation of Highway Bridge Pile Foundation", It realized pile length calculation, the single pile compression calculation, internal force calculation and reinforcement calculation of cylinder pile foundation, further more, on the basic of that draw a diagram of reinforcement structure of pile Foundation.The research result of the thesis makes engineering design personnel liberate from heavy manual calculation. It is of the important practical value to the highway bridge pile foundation for the design and calculation.
