An Improved CRR-Vs1 Characterization Model for Sand-Like Gravelly Soils Validated by Dynamic Centrifuge Tests
Publisher: American Society of Civil Engineers
Abstract: Liquefaction of natural deposited sand-like gravelly soils has been widely reported in past earthquakes. Assessing the liquefaction resistance (CRR) of sand-like gravelly soils in a cost-effective and reliable way raises ...
Verification of the Soil-Type Specific Correlation between Liquefaction Resistance and Shear-Wave Velocity of Sand by Dynamic Centrifuge Test
Publisher: American Society of Civil Engineers
Abstract: Liquefaction of granular soil deposits is one of the major causes of loss resulting from earthquakes. The accuracy of the liquefaction potential assessment at a site affects the safety and economy of an engineering project. ...
Curved Raypaths of Shear Waves and Measurement Accuracy of Bender Elements in Centrifuge Model Tests
Publisher: American Society of Civil Engineers
Abstract: In-flight measurement of shear-wave velocity (
Curved Raypaths of Shear Waves and Measurement Accuracy of Bender Elements in Centrifuge Model Tests
Publisher: American Society of Civil Engineers
Abstract: In-flight measurement of shear-wave velocity (Vs) in centrifuge model test is important for real-time characterization and has multiple engineering applications. Accurate measurement of Vs by bender elements (BE) in ...
Large-Scale Modeling and Theoretical Investigation of Lateral Collisions on Elevated Piles
Publisher: American Society of Civil Engineers
Abstract: Large deflection is mobilized in elevated piles of nonnavigable piers and some flexible protective systems subjected to lateral ship collisions. Because the current bridge design specifications are only suitable for the ...
Dependence of Gas Collection Efficiency on Leachate Level at Wet Municipal Solid Waste Landfills and Its Improvement Methods in China
Publisher: American Society of Civil Engineers
Abstract: Landfill gas (LFG) collection efficiency is low at many municipal solid waste (MSW) landfills in China. The relevant mechanism and potential solution for this problem are studied through laboratory gas permeability tests ...
Gas Pressure Model for Layered Municipal Solid Waste Landfills
Publisher: American Society of Civil Engineers
Abstract: A mathematical model for calculating gas pressure profiles in layered landfill systems is presented. Solutions to scenarios considering a zero-pressure top boundary condition and a zero gas flux or fixed gas pressure bottom ...
One-Dimensional Transient Analytical Solution for Gas Pressure in Municipal Solid Waste Landfills
Publisher: American Society of Civil Engineers
Abstract: Landfill gas (LFG) is generated in municipal solid waste (MSW) landfills because of the decomposition of degradable components. Gas pressure within the landfilled MSWs is of importance as cover or landfill stability may ...
Design Charts for Contaminant Transport through Slurry Trench Cutoff Walls
Publisher: American Society of Civil Engineers
Abstract: Slurry trench cutoff walls with low-permeability backfill material, such as soil-bentonite and slag-cement-bentonite, are used widely for containment of subsurface pollution. In the design of slurry walls the potential ...
