INVESTIGATION OF INSTALLATION STRESSES IN STEEL TUNNEL LINER

FULL SCALE LOAD TESTS WERE PERFORMED ON STEEL TUNNEL LINER SEGMENTS BEING DEVELOPED FOR USE IN SUBWAY TUNNELS OF THE WASHINGTON METROPOLITAN AREA TRANSIT AUTHORITY. TEST LOADS SIMULATING JACKING FORCES REQUIRED TO ADVANCE THE TUNNELING SHIELD WERE APPLIED TO DETERMINE SKIN PLATE BUCKLING RESISTANCE OF THE SEGMENTS. STRESSES CAUSED BY TWO BASIC TYPES OF JACK SHOES WERE INVESTIGATED AS WELL AS VARIOUS TYPES OF SKIN PLATE BRACING. TEST RESULTS WERE COMPARED WITH THEORETICAL CALCULATIONS OF FLAT PLATE BUCKLING LOADS. BASED ON TEST RESULTS AND SUBSEQUENT STRUCTURAL ANALYSIS, A BASIC FABRICATED STEEL TUNNEL LINER DESIGN WAS PREPARED FOR THE WASHINGTON TUNNELS WHICH PROVED MORE ECONOMICAL THAN INITIAL DESIGNS BASED ON STRUCTURAL THEORY ALONE. /AUTHOR/
