MEASURING THE STRUCTURAL PERFORMANCE OF CAST IRON TUNNEL LININGS IN THE LABORATORY

The structural behavior of bolted cast iron segments has been investigated under simple, known loading conditions. This knowledge was required to help ascertain the structural behavior of segments in actual tunnels where complex loading conditions exist. One of two kinds of segment studied was an experimental segment of unusual proportions. Some structural properties of tunnel segments for which evidence had previously been inconclusive were clearly displayed by these experimental segments. Among the conclusions drawn are that the modulus of flexural rigidity of the segments is changed by variation in the applied bending movement, and also with variation in uniform pressure on the back of the segment. The joints between segments do not always behave as simple butt joints.
