Consolidation and Hydraulic Properties of Sand–Biochar and Lightly Cemented Sand–Biochar Mixtures
(American Society of Civil Engineers, 2025)Soil–biochar mixtures have been increasingly investigated for geotechnical applications (e.g., landfill cover system and roadway stormwater filter). However, biochar particles have lower stiffness and strength than soil ... -
Consolidation Analysis of Dredged Slurry Treated by Crosswise-Arranged Prefabricated Horizontal Drains: Analytical and Experimental Insights
(American Society of Civil Engineers, 2024)The use of prefabricated horizontal drains (PHDs) combined with vacuum preloading (VP) has emerged as a popular dredged slurry treatment strategy. However, few theoretical contributions are available to assess its consolidation ... -
Component and System Reliability Assessment of Landfill Cover Systems Using Pseudostatic and Pseudodynamic Methods
(American Society of Civil Engineers, 2024)This paper assesses the reliability of landfill veneer cover systems against direct-sliding failure (DSF) and uplifted-floating failure (UFF) modes using the second-order reliability method (SORM). Variability in stability ... -
A Modified Newmark Analysis of Lateral Spreading Based on Liquefaction Initiation Time
(American Society of Civil Engineers, 2025)The displacement of lateral spreading induced by liquefaction is of great interest to engineering practice. In this paper, a modified Newmark sliding block method was proposed to predict the displacement magnitude of lateral ... -
Comparative Analysis of Longitudinal Seismic Responses of Rigid, Flexible, and Semirigid Immersed Tunnels Using the Analytical Method
