Assessment of Tunnel Excavation on Surface Settlement
The expansion of underground structures is important in urban areas with high population density. In most large cities in the world, urban development is spreading along the structures. These structures are generally located at shallow depth; therefore study of shallow tunnels in urban areas is critical for development. During the excavation of tunnels in urban areas, creating the asymmetric se...
متن کاملAssessment of Soil cohesion of Soils on Tunnel Excavation
Excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. Undergoing the phenomenon in a soil can cause the effective stress and hence the shear strength of the soil to decrease considerably and large deformations happen in the area. Generally, increasing the pore pressure occurs under the undrained condition. If it can be formed the drain...
متن کاملFinite Element Method Analysis of Influence on Subway Tunnel Adjacent to Excavation by Excavation Construction
The interaction influence on subway tunnels adjacent to foundation excavation was produced by excavation construction, and it is great significance for the correct assessment of its size and influence on the safety of subway operation. Based on the foundation excavation project, some typical foundation excavation profiles are selected, the calculation and analysis on additional settlement and h...
متن کاملProbabilistic risk assessment of excavation performance in tunnel projects using Bayesian networks: a case study
A model for probabilistic assessment of excavation performance of tunnel projects is presented. The model is based on Dynamic Bayesian Networks (DBN) and enables to consider the quality of the design and construction process. It is applied on a case study, the excavation of a road tunnel by means of the New Austrian Tunnelling Method. The influence of main model parameters and assumptions (e.g....
