Abstract:Tests for four circular segmented tunnel linings are described. Two single-ring specimens had the conventional flat joint and the tongue-and-groove joints at the key segment. The three-ring specimens used a staggered arrangement and had circumferential joints with and without tongue-and-groove configurations. The load was applied from the top and the side wall on the single-ring specimens. The measurements of overall deformation, joint slip at the key segment, and joint opening were used in studies of waterproofing joints of several linings. The type of joint configurations that has been proven satisfactory is the key segment with the tongue-and-groove for the longitudinal joint. This selection is based largely on economic factors. Documented field cases observed in the underground excavations carried out for the electric utility tunnels in the urban areas were presented to investigate the applicable watertightening joint of segmented linings.
