Application Research on Graphical Technique to Design for the Shield Shell

The generating of binary decision diagram （BDD） Algorithm theory is introduced to prevent the traditional complex abakytics in the shell designing and calculation. The working principle and structure of earth pressure balance shieht are illustrated. The shield shell bears radial external pressure instead of axial external pressure, according to such charaeteristics, the correctness and validity of the empirical equations results are identified by BDD Algorithm. The analysis and comparison indicated that BDD Algorithm can improve the intuition and validity of shell structural design in shield machine. Finally, the satisfied result is achieved.
