RISExperimental Study on the Stability of Railroad Silt Subgrade with Increasing Train Speed
Publisher: American Society of Civil Engineers
Abstract: The comfort and safety of a moving train is largely determined by the dynamic response of the railway track and its foundation (i.e., subgrade). To study the dynamic stability of a silt subgrade subjected to train traffic ...
Vibration Reduction of Plane Waves Using Periodic In-Filled Pile Barriers
Publisher: American Society of Civil Engineers
Abstract: The frequency dispersion characteristics of pile barriers are receiving more attention due to their effectiveness and a better understanding of their behavior at attenuating middle and lower frequency ground vibrations. ...
Application of Periodic Theory to Rows of Piles for Horizontal Vibration Attenuation
Publisher: American Society of Civil Engineers
Abstract: One of the most important phenomena in periodic structures is the existence of the band of frequency gaps (BFGs). Elastic waves with frequencies in BFGs cannot propagate in the medium. Therefore, the BFGs can be used to ...
Modeling Investigation of Different Methods to Suppress Engine Knock on a Small Spark Ignition Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Knock is the main obstacle toward increasing the compression ratio and using lower octane number fuels. In this paper, a small twovalve aircraft spark ignition engine, Rotax914, was used as an example to investigate different ...
Ultrasonic Lift Measurement Technique for Flow-Induced Structural Vibrations
Publisher: American Society of Civil Engineers
Abstract: Deficiencies exist in our current ability to measure lift forces in wind-tunnel experiments on vibrating structures in a fluid flow. The ultrasonic lift measurement (ULM) technique has been previously developed to measure ...
Experimental Study and Simulation of Thermal Conductivity of Saturated Frozen Soil
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this study was to enhance the accuracy of predicting the temperature field of frozen soil and to reduce the workload of thermal parameter testing. To achieve this, we employed a three-phase model comprising soil, ...
Exploring Early Carbonation Properties of Sr4Al6O12SO4 Compound for a Sustainable Alternative to Cement Clinker
Publisher: American Society of Civil Engineers
Abstract: AbstractSr4Al6O12SO4 is a compound that can be used as a sustainable alternative to cement clinker for
producing low-carbon precast concrete products. In this study, we examine the impact
of CO2 curing on early carbonation ...
Application of PIV Technique in Model Test of Frost Heave of Unsaturated Soil
Publisher: ASCE
Abstract: Frost heave of soil is a highly nonuniform problem, in which the local deformation is much more severe and meaningful compared with the overall deformation. When soil is upon freezing, a water–ice phase change occurs and ...
Mechanical Properties of Subgrade Soil Reinforced with Basalt Fiber and Cement under Freeze–Thaw Cycles
Publisher: American Society of Civil Engineers
Abstract: The stability of soil is an essential requirement for various geotechnical engineering projects. The application of composite materials made from cemented soil has become prevalent in road subgrade engineering and foundation ...
Thermal Conductivity of Seawater Cement-Based Materials: Effect of Water-to-Cement Ratio, Curing Age, Sand Content, and Porosity
Publisher: ASCE
Abstract: The microstructures of seawater cement-based materials normally are influenced by the salinity in seawater, which could result in different properties. The thermal conductivity (λ-value) of seawater cement-based materials ...
