The load entering from the ground surrounding on the tunnel’s lining is one of the effective parameters in the designation of a tunnel. The amount of this parameter, which is called Rock load in a rocky environment, depends on several factors such as the overburden thickness, geological and geomechanical conditions and the depth of tunnel. In the present study, the amount of rock load for the L...

Qomroud water conveyance tunnel (lot 1&2) with the length of 16 kilometers is considered as one of the greatest development and national projects in Iran. Since about 2 kilometers of tunnel pass through alluvium and the rest of the tunnel pass through various types of geological units, and due to the complexity of geological condition and variety of effective criteria, suitable selection of exc...

ground settlement due to the shallow tunneling in urban areas can have considerable implications for aboveground civilinfrastructures. engineering geological characteristics of the tunnel host ground including geotechnical parameters of surrounding soil,groundwater situation, and in situ stress condition are amongst the most important factors affecting settlement. in this research, groundsettle...

This paper has made a qualitative and quantitative analysis by establishing the tunnel fault tree and giving the minimal cut sets of the faults in tunnel, and tested the data in tunnel combined with artificial neural network. The fault detection mechanism in this article has been simulated by MatLab and processed a lot of the actual data through the tunnel operating history. Experimental result...

throughout the history, there have been deep cultural as well as scientic connections between iran and india. in medieval period, many persian physicians immigrated to india mainly because of political and social reasons. a good example of this was mirza mohammad hashem alavi khan shirazi who belonged to shiraz medical doctrine. he was born in shiraz, but immigrated to india and was in the cou...

In this study, the reaction of germination and plantlet growth different chickpea cultivars (Arman, Azad, Binalood and Hashem) in relation to osmotic stress due to polyethylene glycol solution (-2, -4, -6 and -8bar) and control (distilled water) using factorial design in completely randomized with four replications was evaluated. In this study, there was a significant difference between the dif...
