Mashhad line 2 metro tunnel excavation impact on ZISTKHAVAR tower and BEHESHTI high school subsidence and analysis stress

Today, the development of urban transportation network is one of the requirements for the development of large cities. Accordingly, the developed countries are compared with the development of transport infrastructure. One of the issues is always a challenge tunneling in urban areas. Possibility of significant settlement during excavation and tunneling operation that caused the problem on the surface structures. Subsidence is related to many factors including local geology, tunnel depth, tunnel height, weight and upper classes, rock mechanical properties (adhesion - the angle of internal friction - Modulus of Elasticity - Young's modulus, etc.), time of water in region, layer, layer the angle of the slope of the layers and types of drilling methods and ... Can be considered. Metro launched today, is one of the country's infrastructure. Each country needs to develop the infrastructure in big cities. Mashhad is a large and densely populated cities Iran. Mashhad line 2 metro tunnel traverse of important buildings such as tower ZISTKHAVAR‚ Impact subsidence is important in structures. in paper‚ examines the environmental subsidence in Tower East High School and was a martyr heavenly ‚ The geological and geomechanical characteristics of towers and high expression has been. Using empirical methods Peck will pay to investigate the pit subsidence and either of Numerical methods and finite element analysis‚ results then is compared together. Damage to towers and high school scholars will discuss the forecasts and these losses will be determined. Longitudinal distance of the conference on empirical methods is created by the surface, will estimate. Induced stresses caused by the tunneling and the maximum tensile stress is given. Subsidence of the tower will estimate the importance of the structure and type of injury that the tower will be based on scientific research and recommend how to prevent this damage examine the impact of subsidence on SHAHID BEHESHTI high school and ZISTKHAVAR towers how much will impact
