Numerical investigation of the effects of geotechnical parameters on building risk level due to mechanized tunneling in urban areas

In this study, the effects of some geotechnical parameters on surface settlement curves due to mechanized tunneling and corresponding risk buildings are investigated through numerical analysis. The advanced constitutive law Plastic Hardening is utilized accurately reflect Soil behavior in unloading. Using obtained from analysis, category calculated effectiveness each parameter level investigated. results show that cohesion friction angle do not have a remarkable effect risk. However, amount overburden soil elastic modulus considerably affect subjected buildings. Recognizing role makes it possible predict potential optimize approaches for mitigating these risks.
