内容記述 |
Because deformation and crack development have been observed in ageing tunnels of Tokyo Electric Power Company, we analyzed the causes and investigated methods for reinforcing the tunnels. Through various investigation, it was determined that the tunnel deformation was caused by increases in the earth pressures acting on the tunnel due to long-term consolidation settlement resulting from the fall of the groundwater level in the ground and the inflow of groundwater into the tunnel. A series of study methods for predicting increases in additional long-term load, evaluating the residual strength of an existing tunnel, judging the necessity of reinforcement to resist additional loading, and determining the time and method of reinforcement was determined, and the reinforcement method was applied to a markedly deformed tunnel in soft cohesive soil ground. |
