DESIGN OF TUNNEL LININGS TAKING ACCOUNT OF THE CONSTRUCTION PROCEDURE

THE DESIGN OF THE TUNNEL LINING IS USUALLY TREATED AS A PLANE PROBLEM, WITH NO ACCOUNT BEING TAKEN OF THE CONSTRUCTION PROCEDURE. THE DISADVANTAGE OF THIS IS THAT THE DEFORMATION OF THE ROCK WHICH TAKES PLACE BEFORE THE LINING IS INCORPORATED IS NOT CONSIDERED. THE AUTHOR SHOWS HOW THESE DEFORMATIONS, WHICH ARE ASSOCIATED WITH THE CONSTRUCTION OF THE TUNNEL, MAY BE INCLUDED IN STATIC DESIGN. IT IS PROVED THAT THE EFFECTIVE PRESSURE OF ROCK ON THE LINING IS TO A LARGE EXTENT DETERMINED BY THE CONSTRUCTION METHOD AND THE STIFFNESS OF THE LINING, AND THAT A KNOWLEDGE OF THE MECHANICAL PROPERTIES OF THE ROCK IS NECESSARY BEFORE CALCULATIONS ARE CARRIED OUT. /TRRL/
