Abstract
<p>Several irrigation tunnels are damaged due to the application of plastic earth pressure for a long period and deformation progresses as time passes. In order to consider the maintenance for these damaged irrigation tunnels, evaluating the damage conditions, such as the convergence of the tunnel lining and cracks, is of crucial importance. This paper compares the numerical results using the RBSM (Rigid Body Spring Model) with the results of model tests for the tunnel lining and the ground under plastic earth pressure. To investigate the applicability of the RBSM, comparisons are made based on the deformation and damage patterns. The results show the numerical validity of the crack point sources and the crack generation loads.</p>
