Numerical 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...
متن کاملwater table management effects on quantity and quality of water drains out of underground drainage
concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...
متن کاملNumerical Modelling of the Segmental Lining of Underground Structures
There are several methods for analysing the behaviour of underground structures under different loading conditions. Most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. On the other hand, for stability analysis and the designing of support systems, these methods consider segme...
متن کاملEvaluation of structural analysis of tunnel segmental lining using beam-spring method and force-method (Case study: Chamshir water conveyance tunnel)
The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...
متن کاملApplication of barley straw to remove nitrate from drainage water
ABSTRACT-Nowadays farmers often use N-fertilizers to increase crop yield, but they lost quickly by leaching causes environmental contaminations that reported as most important source of pollutant. Although biofilters are useful for removing nitrate from drainage water, but many researches show that they need an external carbon source to sustain denitrification. Many researchers study on differe...
