External "shell" stops soil movement and saves tunnel
Tunnel distortion caused by shifting soils posed threat to Southern Pacific rail traffic along San Francisco Peninsula; to solve problem, supplementary structure was designed to form protective "shell" around tunnel which could be installed externally without interruption to Southern Pacific rail service; "shell" consists of two rows of wide-flange steel piles, one row on either side of tunnel; they are tied together above tunnel by other wide flange members.
