Abstract：A 2D graphical model preprocessor(2D-GMS) is given for geometrical modeling in numerical analysis tools,which is the update of the preprocessor of ZSlope developed earlier.Based on the object-oriented techniques and the creative graphic-element-relation restriction mechanism,the 2D-GMS can verify the geometrical constraints of the established models automatically,reducing the error probability due to the engineers’ carelessness and improving the operational reliability.This paper provides the comparison of functions of load modeling among 2D-GMS,Geo-Slope and Slide.The results show that the function of load modeling in 2D-GMS is of more efficiency and reliability than that in Geo-Slope and Slide to a certain degree.
