RISAn Analytical Model for Water Inflow into a Karst Tunnel in Vuggy and Fractured Porous Rock Aquifers
Publisher: ASCE
Abstract: Vugs and fractures are the main channels within porous rock aquifers and play a dominant role in the water inrush of the karst tunnel. In this paper, a mathematical model of the coupled free-fluid seepage-fluid with ...
Discrete-Element Numerical Investigation of the Dynamic Response Characteristics and Instability Mechanism of a Cross-Jointed Rock Mass Slope under Multistage Sustained Seismic Action
Publisher: American Society of Civil Engineers
Abstract: Frequent earthquakes, coupled with discontinuous geological conditions, complicate the earthquake dynamic response characteristics of slopes. To reveal the dynamic accumulative damage effect and instability mechanism of a ...
Preparation and Properties of Cold-Mixed Epoxy-Asphalt Mixture Based on Fractal Theory
Publisher: ASCE
Abstract: Cold-mixed epoxy-asphalt mixture (CMEAM) has gradually received increased attention in steel bridge pavement construction due to its excellent road performance and low harmful gas emissions. According to previous studies, ...
Remediation of Coal Tar–Contaminated Soil by Smoldering Combustion Using Vegetable Oils as Supplemental Fuel
Publisher: ASCE
Abstract: This study explored the remediation of coal tar–contaminated sand with smoldering combustion using vegetable oil as supplemental fuel. In this work, bench-scale column experiments were conducted one factor at a time to ...
Development of the Asphalt Foaming Performance Evaluation System Based on Binocular Ranging Technology
Publisher: American Society of Civil Engineers
Abstract: Due to the lack of essential understanding of asphalt foaming behavior, engineering problems such as mix design failure and unstable performance of foamed asphalt cold recycling mixtures are prone to occur. This paper ...

Data-Driven Approaches for Characterization of Aerodynamics on Super High-Speed Elevators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modeling and characterizing high-dimensional aerodynamic pressures, on the elevator in the hoistway, is very challenging. An accurate model is helpful to understand and analyze the pressure characteristics, which is a vital ...
Permeability Characteristics of Porous Rock with Conduits under Stokes–Brinkman–Darcy Coupling Model
Publisher: ASCE
Abstract: Conduits, the main channels within a rock mass, can significantly affect the permeability characteristics of rock masses. This paper presents a Stokes–Brinkman–Darcy coupling model to study the permeability characteristics ...
Dynamic Energy Evolution Mechanism and Viscoelastic Damage Constitutive Model of Frozen Soil under High Strain Rates
Publisher: American Society of Civil Engineers
Abstract: This study investigated the dynamic energy evolution mechanisms and failure behaviors of frozen soil subjected to impact loading. A split Hopkinson pressure bar was utilized to perform impact compression tests on frozen ...
