Improved Theoretical Solutions for Estimating the Tunnel Response Induced by Overlying Excavation

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...

Finite 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...

Surface Movements in a Rock Massif Induced by Drainage Associated to Tunnel Excavation

Dynamic Bayesian Network for Probabilistic Modeling of Tunnel Excavation Processes

A Dynamic Bayesian Network (DBN) model for probabilistic assessment of tunnel construction performance is introduced. It facilitates the quantification of uncertainties in the construction process and of the risk from extraordinary events that cause severe delays and damages. Stochastic dependencies resulting from the influence of human factors and other external factors are addressed in the mo...
