Optimum Design CAD System Of Detached And Supple Foundation Of Electricity Transmission Tower

Nowadays, there is a big development in electric power projects. And every year our country spents lots of construction investment on it. However, although the foundation of electricity transmission tower with a big scale has many softwares on it, few can use in real projects. People always design foundations in design institute by handwork. That greatly increases the amount of work, and is very inefficiently. Aim at this problem, a CAD optimum design system of detached and supple foundation of electricity transmission tower has been studied in this paper. The system uses an easy and efficient method named Grid Search to find out the minimum cost of an detached and supple foundation. At the same time, the immerge of foundation,the width of column, the thickness and width of foundation plan have been ascertained. And the steel bars will be matched also. It is an integrative system with calculation and drawing.The system uses Windows XP as the developing platform and VC++6.0 as the developing tool and AutoCAD as the graphics-supporting environment. The system also employs the C/C++ programming technique under the Windows operating system, the MFC foundation class library, AutoCAD developing tool-ObjectARX and other techniques. The system is established using the Object-oriented programming method, it hasrelatively high stability and efficiency.The sysytem incorporates the traditional design method with optimum method. It can make the design not only simple, exact and high-efficiency, but also economical. When the essential information of load info, geologic condition, concrete grade, steel grade, material price and range of foundation size, etc. are given, the system can completes the whole process of internal force analysis, the optimization design of foundation size and reinforced bar, the drawing of construction drawing.
