These guidelines, prepared by Working Group 2 (Research) of the International Tunnelling Association, are presented in three parts: Part I describes the outline of the procedure of design. Part II presents the detailed design methods. Part III provides references, including examples of design. Because the methods of designing shield tunnel linings vary, the guidelines do not recommend that priority be given to any one method. Rather, this report presents the basic concepts of shield tunnel linings, in order to provide reference and guidance in designing tunnel linings.
