| Abstract: | By the analysis and study on the character and design method for cross section of interchange ramp, the component template models and the group sides models for roadway and side slope are presented. The data structure for th ese models is also developed. By dividing the joint area into 5 parts, a curve f ace model and its formula for the joint area design are established. The results indicate that these models and formulas can improve the flexibility of intercha nge CAD and raise efficiency for interchange design. |
