Polymer-Impregnated Concrete Tunnel Support and Lining
The development of precast polymer-impregnated concrete (PIC) tunnel support-liner systems is reported. Investigations included: (1) Full-scale tests of conventional concrete and PIC segments with concrete backfill as well as PIC segments with sand backfill; (2) economic studies to compare precast conventional concrete and PIC systems; (3) the effects of joint configuration, elastromeric joint sealer, and segment material on the support-lining system strength determined by laboratory tests and statistical inference; (4) heat transfer analysis employing finite differences to determine temperature distribution in the PIC lining caused by transportation tunnel fires; (5) effects of elevated temperature on the compressive strength and the heat transmission characteristics of PIC; and (6) determination of flame spread, fuel contribution, smoke developed, the combustion gases, and visual damage of PIC resulting from exposure.
