Abstract The karst caves whose diameter is more than 1m at the depths of 0~13 m were the objects in the exploration of concealed karst of Gui-Guang Railway. Landsonar was used in the tunnel part, and 4491 karst caves more than 1m in diameter were marked along the 68km surveying line. As there is no ready-made software and standard to draw the achievement graphs in karst cave exploration, the means put forward in this paper are the best methods to take the advantage of the secondary development of AutoCAD to program a software and draw the graphs.
