The portable computer CASIQFX-4800P was applied to programming calculation in order to calculate coordinate.

By combining the formula of Simpson with the programming calculation of CASIOfx-4800P computer, the paper calculates the coordinates of center-line points and boundary-line points of roads, and then lays out the point sites of center-line points and boundary-line points of roads with the help of the electronic total station.

This paper presents a method to differentiate the closing link with respect to the component links in a plane dimension chain distinguishedHaving determined the increasing link or the decreasing link of the component link,it is convenient to solve the dimension chainThis method is very suited to computer programming,and a practical example is give

To conduct regular evaluations such as financial, technical program risk analysis, value engineering, and other aspects of computing in process of project management are more complicated calculation, and the computer programming needs specialized language environment.

Therefore,based on the analysis of the relationship between cross section width and cross section height and total cost,the two-dimension golden section method and computer programming methods are introduced to solve the problem by the author.

Taking a certain engineering as the example, this paper introduces in detail the application of AutoCAD, total station and program calculator in the engineering survey.
