摘要：
Joints are provided between the members of a pair of elements, such as a pair of concrete tunnel lining segments which are secured together in compression by a fastening arrangement with a gasket between the end faces of the segments. The gasket has a multiplicity of spaced recesses or apertures to prevent the gasket from creating a surface tension in the end faces when the joint is subjected to compression.
