要旨 Stress generation at the crown in the second lining concrete of NATM double shell lining systems was studied using a finite element based system. The results of numerical simulation were compared to actual tunnel measurements in a past research. It was revealed that before the form removal, stress generation in the hoop direction leading to longitudinal cracking was governed by temperature variations. After the form removal, stress behaviour was governed by both self-weight and temperature decrease.
