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 کاملA numerical analysis of effect of segmental lining joints on tunnel support internal forces under seismic loading
During an earthquake, the better performance of segmental tunnel lining, compared to the continuous in-cast concrete lining, is generally related to the joints between segments. In order to better understand the influence of the segment joints, their effect on the internal forces induced in tunnel lining simultaneously with the effects of the other influential parameters should be considered. I...

متن کاملenvironmental impacts of urban utility tunnel construction (case study: urban utility tunnel district 22 of tehran)
urban facilities are necessary components of cities. in all grown and developed cities of the world there are tremendous network of facilities such as water and electric ties, water sewage drainage, water piping and gas piping. that has not been installed in proper depth underground and locations and with growing of the cities and consumption of population. they need to be replaced by excavatin...
متن کاملEffect of Segmental Joint on Internal Forces in Tunnel Lining under Seismic Loading by Numerical Method
Although segmental tunnel linings are often used for seismic areas, the influence of segment joints on the segmental lining behavior under seismic loading has not been thoroughly considered in the literature. This paper presents the results of a numerical study investigating the effects of the rotational, axial, and radial joint stiffness of the longitudinal joints on the structural force...
