トンネル覆工の構造耐力の決定メカニズムに関する実験的考察

抄録

Full-scale model tests simulating tunnel concrete lining were carried out to clarify collapse mechanism of tunnel lining under a few kinds of load condition and reinforcing material. For the design of tunnel lining, the limit states of lining cross section were defined, however, the limit state of the section was found to be different from the structural one. Load-carrying capacity will be calculated more rationally and it leads to proper structure, reduction of construction cost and improvement of its durability by considering these results for the design.
