Numerical simulation of water entry of tunnel cross section with different deadrise angles and tunnel radiuses
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
متن کاملAnalytical 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 کاملDeformation Monitoring of Metro Tunnel with a New Ultrasonic-Based System
With the rapid construction of metro tunnels in many metropolises, a fast and convenient solution to capture tunnel deformation is desired by civil engineers. This contribution reports an automatic and wireless tunnel deformation monitoring system using ultrasonic transducers. A processing algorithm of the redundant ultrasonic information (RUI) approach is proposed to improve measurement accura...
متن کاملCross Section Effects on Convergence-Confinement Method in Multi Stage Tunnel Excavation
Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...
متن کاملAccuracy Analysis of the Leica Hds3000 and Feasibility of Tunnel Deformation Monitoring
Deformation monitoring with total stations, while superior in accuracy, suffers from the poor spatial resolution obtainable by this measurement method within the limited time on a tunnel construction site, and deformation can only be detected at previously marked target points. Due to its high speed in obtaining unstructured point clouds from all surfaces within the field of view terrestrial la...
