An optimal method to design reinforced concrete lining of pressure tunnels
The utilization of the lining type in pressure tunnels is highly dependent on the geological and hydraulic conditions. There are two types of lining, namely concrete and steel lining but steel lining is one of the most expensive arrangements. To decrease the length of steel lining in these tunnels, the concrete lining, which prevents water seepage from the surrounding rock mass, is the appropri...
متن کاملRisk-based Replacement Strategies for Deteriorating Reinforced Concrete Pipes
Water distribution networks comprised of underground reinforced concrete pipes deteriorate with time due to environmental conditions, such as chloride-induced corrosion and differential soil movements [1]. If the pipes in these networks are not periodically replaced, they will eventually fail. Strategies for replacement for these pipes depend on 1) the risks associated with failure of a water d...
متن کاملA comparative study of two meta-heuristic algorithms in optimizing cost of reinforced concrete segmental lining
In this work, we tried to automatically optimize the cost of the concrete segmental lining used as a support system in the case study of Mashhad Urban Railway Line 2 located in NE Iran. Two meta-heuristic optimization methods including particle swarm optimization (PSO) and imperialist competitive algorithm (ICA) were presented. The penalty function was used for unfeasible solutions, and the seg...
متن کاملAnalysis of the Effect of Fluid Velocity on the Instability of Concrete Pipes Reinforced with Nanoparticles Conveying the Fluid Flow
With respect to the great application of pipes conveying fluid in civil engineering, presenting a mathematical model for their stability analysis is essential. For this purpose, a concrete pipe, reinforced by iron oxide (Fe2O3) nanoparticles, conveying fluid is considered. The goal of this study is to investigate the structural stability to show the effects of the inside fluid and the nanopart...
متن کاملStrength and Toughness of Reinforced Concrete with Coated Steel Fibers
The effect of zinc phosphate (ZP) and zinc calcium phosphate (ZCP) coatings on the reinforcing mechanisms of smooth steel fiber in cementitious matrix have been studied. The results of pull out tests illustrated that by coating smooth steel fiber the pull-out load may be increased up to 100%. The effect of zinc phosphate coating on interface bonding was more than zinc-calcium phosphate coating....
