Solution to Ruptured Line of Terrain by DEM Based on Yang Chizhong Method

CHEN Tian-wei(College of Civil Engineering and Architeture,Guilin University of Technology,Guilin 541004,China)  
According to the problems in dealing with the rupture lines by ridding DFM,and the process of DEM conformation in Yand Chizhong Method,the estimation and disposal arithmetic of unknown points and known discrete points above the rupture lines and on both sides are put forward in this article.Clockwise direction,anticlockwise direction,high points,low points and line bestriding are examined by vector cross product.Experiments prove new arithmetic method to be correct and feasible.
