RISTheoretical Analysis of the Joint Leakage in Shield Tunnel Considering the Typical Deformation Mode
Publisher: ASCE
Abstract: The joint leakage in a shield tunnel is a common defect and difficult to be accurately quantified due to the complex deformation mode and stress state, which seriously threatens the service performance of the tunnel lining. ...
Adaptive Quadratic Sum-Squares Error for Structural Damage Identification
Publisher: American Society of Civil Engineers
Abstract: The ability to detect damages online, based on vibration data measured from sensors, will ensure the reliability and safety of structures. Innovative data analysis techniques for the damage detection of structures have ...
Reliability Analysis of Slope Stability Considering Uncertainty in Water Table Level
Publisher: ASCE
Abstract: Geotechnical analysis and design are usually based on traditional methods and empirical relationships. However, various challenges, such as the inability to model all parameters involved and the uncertainty of model input, ...
Effect of Normal Transformation Methods on Performance of Multivariate Normal Distribution
Publisher: ASCE
Abstract: Multivariate normal distribution is used widely to characterize the uncertainties and correlations for correlated geotechnical data. The success of constructing a multivariate normal distribution depends on the reliable ...
Investigating the Effect of Geological Heterogeneity of Strata on the Bearing Capacity of Shallow Foundations Using Markov Random Field
Publisher: ASCE
Abstract: Geological heterogeneity is a result of the natural deposit process of strata with a highly irregular and uncertain distribution of soil mass in the real world. However, compared with the effect of inherent spatial variability ...
Probabilistic Analysis of Tunnel Roof Deflection under Sequential Excavation Using ANN-Based Monte Carlo Simulation and Simplified Reliability Approach
Publisher: ASCE
Abstract: Tunnel roof deflection is an important measure to control the safety of excavation activity, especially for large-section tunnels using the sequential construction method. A three-dimensional (3D) model of a sequential ...
Quantitative Risk Assessment of Cut-Slope Projects under Construction
Publisher: American Society of Civil Engineers
Abstract: In some cut-slope projects landslide is a common problem during construction due to unfavorable geomorphological and geomechanical conditions. It is necessary to do a quantitative assessment of the risk posed by landslide ...
Time-Dependent Fragility Functions for Circular Tunnels in Soft Soils
Publisher: ASCE
Abstract: Fragility functions are used in the vulnerability analysis of structures considering different sources of uncertainties. In this research, a framework to develop time-dependent fragility functions for circular tunnels ...
Resilience-Based Strategies for Topology Enhancement and Recovery of Metrorail Transit Networks
Publisher: ASCE
Abstract: Metro networks are complex systems that provide efficient and reliable transportation services for communities and play prominent roles in sustaining local economies, yet investments and safety enhancements to the networks ...
A Novel Gegenbauer Wavelet-Based Approach for Stability and Surface Location Error Analyses of Milling Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a novel wavelet-based method for the computation of the milling stability and surface location error (SLE). The governing equation of milling processes considering the self-vibration and forced-vibration ...
