RISHigh-Cycle Computational Model for Accumulative Deformation of Granular Material under Repeated Traffic Loading
Publisher: ASCE
Abstract: The ballast, essentially unbound granular material, contributes more than 50% to the total settlement of the ballasted railway track, greatly affecting the safety and comfort of train operation. To reduce the deformation-related ...
Measuring Dielectric Constant in Highly Conductive Soils Based on Surface Reflection Coefficients
Publisher: American Society of Civil Engineers
Abstract: In soils with high electrical conductivities, time domain reflectometry (TDR) principles fail to measure the apparent dielectric constant by travel time analysis. This limits the application of water content measurement ...
Estimation of Maximum Liquid Depth in Layered Drainage Blankets over Landfill Barriers
Publisher: American Society of Civil Engineers
Abstract: Based on an extended form of the Dupuit assumption, this technical note proposes a computational solution for calculating the maximum liquid depth
New Load Transfer Hyperbolic Model for Pile-Soil Interface and Negative Skin Friction on Single Piles Embedded in Soft Soils
Publisher: American Society of Civil Engineers
Abstract: A proper load transfer model describing the pile and surrounding soil interaction is important for accurately predicting the behavior of piles. In this paper, a new load transfer hyperbolic model for the pile-soil interface ...
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 ...
Evolution of Soil Arching in Geosynthetic-Reinforced Pile-Supported Embankment of a High-Speed Railway under Long-Term Train Traffic Loading and Excessive Subsoil Settlement
Publisher: American Society of Civil Engineers
Abstract: Soil arching formed in geosynthetic-reinforced pile-supported (GRPS) embankments of high-speed railways plays an important role in transferring the forces within the embankments. In most cases of notable settlements and ...
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 ...
Mechanical Characteristics and Planting Performance of Ecological Concrete Produced Using Low-Quality Aggregate
Publisher: American Society of Civil Engineers
Abstract: AbstractLow-quality rocks obtained from engineering excavation generally are considered to
be unsuitable for direct application and are typically discarded. This practice results
in challenges such as land utilization and ...
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. ...
