The total structure ， main functions and key techniques of general design software of a prestressed anchor (common) slide-resistant pile are introduced briefly. On the basis of the AutoCAD, and by using object-oriental program design language, such as Visual Basic, Visual Lisp etc., the software can constructe a geological model simulating a slide mass, which can divide slope body into slices automatically, and acquirie geometry parameters of each slice for stability calculation automatically. It is very easy to complete the work flow from constructing slope model to computing slope stability and finishing the design of the slide-resistant pile using the system. The results obtained by means of engineering examples tests show that it has such many advantages compared with the same kinds of software so as to be worthily spreaded, which include simple modeling, convenient operation, high automation, reliable result and quick export etc.
