Discussion on Tunnel Design: Philosophy and Practice by T.W. Hulme

Mr. E. F. Glover (DTp): I have one question for Mr Hulme concerning the importance of the time element before the erection of temporary or permanent lining. Some experiments were made by the Building Research Establishment on the Kielder Dam Scheme, as part of the preliminary works, to establish how long it took to obtain a balance between the maximum pressure on the lining using minimum materials.
