Seismic performance evaluation of Precast Concrete Lining (PLC) using the 1/5 scale down model test

Precast Concrete Lining (PCL) is invented in order to resolve the problem of the cast-in-place concrete lining in Norway. However PCL could not consider the effect of earthquake because an earthquake rarely occurs in the region of Northern Europe. Consequently, the analysis of the effect of earthquake on PCL should be made before introducing PCL to Korea. The purpose of this research is to evaluate the stability of tunnel applying PCL in the case of earthquake. To evaluate the seismic performance of PCL, we used shaking table apparatus by 1/5 scale down model. The result of this research is as shows that deep tunnells satisfied for Korea seismic design criteria.
