RISRelationship between Porosity and the Constitutive Model Parameters of Rockfill Materials
Publisher: American Society of Civil Engineers
Abstract: In this study, triaxial tests are performed on rockfill material (weakly weathered fresh tuff) with different porosities in order to obtain the stress–strain curves of the test specimens. The confining pressure and porosity ...
Potential Applications of Phase Change Materials to Extend the Winter Construction Time of Earth-Rock Dam in Cold Regions
Publisher: ASCE
Abstract: During earth-rock dam construction, temperature control to reduce the freeze–thaw impact on core-wall clay in cold regions is difficult. To address this challenge, this research developed a phase change material (PCM) ...
Interlayer Aggregates Embeddedness Index and Its Characterization for Interlayer Bonding Quality of Roller-Compacted Concrete
Publisher: ASCE
Abstract: Interlayer bonding is one of the critical principles of roller-compacted concrete (RCC) construction. The fundamental premise of ensuring interlayer bonding quality is embedding interlayer aggregates (IAs) into the lower ...
Mechanism of the Freeze–Thaw Deterioration of Clay Incorporating Phase Change Material
Publisher: American Society of Civil Engineers
Abstract: During winter construction of earthworks such as earth dams and embankments, the structural properties of the soil may deteriorate due to freeze–thaw cycles. A new measure to combat freeze–thaw damage, incorporating phase ...
Integrating Building Information Model and Augmented Reality for Drone-Based Building Inspection
Publisher: ASCE
Abstract: Unmanned aerial vehicles (UAVs) have been widely accepted for building inspection in recent years. However, the advantages of UAV inspection are not fully leveraged because of the absence of related information to assist ...
Multisensory and BIM-Integrated Digital Twin to Improve Urban Excavation Safety
Publisher: ASCE
Abstract: Urban excavation is an indispensable process for many construction activities such as road paving, house building, and pipe rehabilitation. However, the everincreasing complexity of underground utilities (e.g., water ...
Long-Term Structural Behavior of Concrete Face Rockfill Dams Considering Fluid–Solid Coupling Effects and Spatial Parameter Variability
Publisher: American Society of Civil Engineers
Abstract: A numerical method is proposed to analyze the long-term structural behavior of concrete face rockfill dams (CFRDs), considering fluid–solid coupling and the spatial variability of model parameters. Initially, a method was ...
Schedule Risk Analysis for TBM Tunneling Based on Adaptive CYCLONE Simulation in a Geologic Uncertainty–Aware Context
Publisher: American Society of Civil Engineers
Abstract: Schedules are fundamental parameters for decision making in the design phase of tunnel construction projects. Schedule estimates of tunnel construction projects are subject to major uncertainties caused by uncertain geologic ...
Integrated Processing of Image and GPR Data for Automated Pothole Detection
Publisher: American Society of Civil Engineers
Abstract: A pothole is a severe pavement distress that can compromise pavement rideability and safety and can be the cause of expensive damage claims. The detection and evaluation of potholes are predominantly manual and time-consuming. ...
Compaction Quality Control of Earth-Rock Dam Construction Using Real-Time Field Operation Data
Publisher: American Society of Civil Engineers
Abstract: Compaction quality is critical to the stability and durability of earth-rock dams. The traditional quality inspection method relies primarily on testing randomly sampled spots of a job site, which may cause unreliable ...
