Analytical analysis of ultimate ground pressure on tunnel support system
The ground reaction curve (GRC) is a vital component of the convergence-confinement method, which possesses many applications in the underground space designs. It defines a relation between the tunnel wall deformations and the ground pressure acting on the tunnel walls. Generally, GRC includes descending and ascending branches. According to many researchers, the descending branch trend for the ...
متن کاملSoil-Interaction of Intake Pressure Tunnels under Ground Strength Reduction Conditions due to Cracking of the Lining (Case study: Dasht-e-Abbas intake pressure tunnel)
The induced cracks on the concrete lining of the intake pressure tunnels may cause the water seep into the surrounding media leading to develop a hydro pressure on the external surface of the lining. In the common design practice, the lining can be designed to tolerate with this pressure using the Schleiss method. However, when the tunnel is constructed above the underground water, the seepage ...
متن کاملPrediction of maximum surface settlement caused by earth pressure balance shield tunneling using random forest
Due to urbanization and population increase, need for metro tunnels, has been considerably increased in urban areas. Estimating the surface settlement caused by tunnel excavation is an important task especially where the tunnels are excavated in urban areas or beneath important structures. Many models have been established for this purpose by extracting the relationship between the settlement a...

متن کاملNumerical Investigation on the effect of the internal water pressure and leakage force on the behavior of tunnel lining
There is a pressure tunnel as the type of structures, which is mainly used in the hydroelectric power industry and in order to design and construct these structures, there are many engineering challenges. One of these problems is the leakage around the tunnel and, consequently, erosion caused by excessive water pressure, and it will lead to instability and the destruction of pressure tunnels. T...
