Efficient Geotechnical Reliability Analysis Using Weighted Uniform Simulation Method Involving Correlated Nonnormal Random Variables
Publisher: ASCE
Abstract: In the context of probabilistic analysis involving uncertain factors, efficient reliability methods play an important role for promoting a wider application in engineering practice. Although the ordinary Monte Carlo ...
Reliability Updating Method with Copula-Based Weighted Low-Discrepancy Samplings
Publisher: ASCE
Abstract: This study proposes an efficient reliability updating method to quickly estimate the low-level failure probability, Pf, in structural/geotechnical systems, along with the identification of the most probable failure point ...
Deep Learning–Based Prediction of Tunnel Face Stability in Layered Soils Using Images of Random Fields
Publisher: American Society of Civil Engineers
Abstract: The stability analysis of tunnel faces in multilayered soils presents challenges due to the inherent variability in natural soils. Although the random field finite-element methods offer a reliable approach to address such ...
New Observations on the Application of LS-SVM in Slope System Reliability Analysis
Publisher: American Society of Civil Engineers
Abstract: The stability evaluation of earth slopes is a common practice in geotechnical designs. To account for uncertain characteristics of soil properties, probabilistic evaluation that requires repeated calculations of factor of ...
Numerical Investigation of Coupled Effects of Temperature and Confining Pressure on Rock Mechanical Properties in Fractured Rock Mass Using Thermal-Stress-Aperture Coupled Model
Publisher: ASCE
Abstract: The mechanical performance of rock mass subjected to the coupled influences of the elevated temperature and in situ stresses has always been a hot topic in underground rock engineering projects. In this study, a ...
DEM Analysis of Dynamic Evolutions of Lateral Soil Arching in Sandy Soil
Publisher: American Society of Civil Engineers
Abstract: For landslide mitigation, stabilizing piles are widely adopted in geotechnical engineering practice. The formation of soil arching between stabilizing piles can greatly mitigate the lateral spreading of sandy soil, and ...
Synergistic Effects of a Combination of Vacuum Ultraviolet–Induced Oxidation and Wet Absorption Process on Removal of Nitric Oxide at Room Temperature
Publisher: ASCE
Abstract: Removal of low concentration NO in enclosed space by a new combined process incorporating vacuum ultraviolet (VUV)-induced oxidation and wet absorption process at room temperature was studied. Effects of NO initial ...
