Development Of CAD System Of Reinforced Concrete Cantilever Retaining Wall

The paper takes the common soil-slope in the slope engineering as an example and analyzes the design process of reinforced concrete cantilever retaining walls, which provides the reasonable and economical method for retaining walls design from the internal-force calculation to the output of work drawing.At present, the retaining walls design is mainly on the bases of workbox and manual drawing, so it is necessary to improve the efficiency of structure design. In order to lighten the burden in structure design, the paper takes advantage of the quick calculation of computer to develop the Computer–Aided Design system of reinforced concrete cantilever retaining walls, combined with the experiences of engineers and also gets good results in the engineering example. Actually, the CAD system is not commonly used in retaining walls design, so the development of CAD system in the area of cantilever retaining walls design will bring more convenience to the structure design.The system is especially developed for the cantilever retaining walls in common use recently on the bases of the actual code for design of concrete structures(GB50010-2002), code for seismic design of buildings(50011-2001), code for design of building foundation (GB5007-2002), the technical code for building slope engineering (GB50330-2002) and the normal design of national building (04J008). There are many functions in the system, including data input in man-machine conversation, model creating, loading calculating, finite element analysis, data output and work drawing display.The system is adapt to Windows XP and developed with the computer language visual C++6.0. There are many advantages in the system such as good result , data output, readability, easy expanding and so on.
