Abstract

The behavior of the tunnel lining under grouting pressure has not been clearly understood yet. Therefore, in this work, we measured stress resultants of a tunnel lining while injecting the grout into the sand layer around it. According to the results of this, several meaningful indication was obtained as follows. In case of injection from a hole for grouting, the bending moment predominated in the short term behavior. Contrary to this, in the long term, the axial compressive force became prominent, when we had injected around the tunnel uniformly. Furthermore, when we injected the grout only one side of the tunnel, the axial tensile force as well as the bending moment grew substantially.
