Abstract |
In this paper, to evaluate and verify safety and performance of new-concept lining board, the experiments and analyses were performed. From the flexural tests, it was noted that the failure occurred at the load of 664kN. At structural analyses based on test results, when the loadings are the unit load 100kN and failure load 664kN, the maximum displacements at the middle part of lining board were 2.58mm and 27.01mm, respectively. In addition, at the elastic range and the plastic range, their load carrying capacities were evaluated as DB-34 and DB-41, respectively. Accordingly, it can be concluded that, since the lining board developed in this study satisfy the design load and structural safety, it supplemented its disadvantages and can apply to construction site.
