Rapid Drawdown Analysis of Levees
(American Society of Civil Engineers, 2025)Rapid drawdown (RDD) is an important stability design condition for the waterside slopes of levees. A framework for levee RDD analysis that evaluates both seepage and undrained shear strength (su) has been assessed in this ... -
Rapid Detection of Landslides for the Timely Response of Disaster Mitigation and Relief
(American Society of Civil Engineers, 2025)Landslides on the Tibetan Plateau can induce disaster chains, which can extend the damage from one point to an area. At present, the timely treatment of landslides after they have occurred is the only feasible way to avoid ... -
Rapid Assessment of Concrete Resistance to Physical Sulfate Attack: Effects of the Binder, the Water-to-Binder Ratio, and the Entrained Air
(American Society of Civil Engineers, 2025)Concrete surfaces in the evaporation zone above sulfate-rich soils are subject to severe damage from scaling. Such a physical sulfate attack (PSA) on concrete is a consequence of a cyclic regime between hot-dry and cold-wet ... -
Railway-Fastener Point Cloud Segmentation and Damage Quantification Based on Deep Learning and Synthetic Data Augmentation
(American Society of Civil Engineers, 2025)Accurate detection and quantification of damage to railway fasteners are crucial for ensuring railway safety. The spatial damage defects caused by the complex shape of fasteners and the problem of data imbalance in actual ... -
Railway Bridge End-Approach Zone under a Moving Load: Numerical Assessment from a Geotechnical Perspective
(American Society of Civil Engineers, 2025)When subjected to moving train loads, the bridge-end transition zone becomes an important geotechnical site, requiring detailed investigation. Dealing with complex track–substructure–soil interaction is essential because ... -
Radial Mixing in Steady and Accelerating Pipe Flows
(American Society of Civil Engineers, 2024)Understanding solute transport in pipe flows is essential for ensuring consistent water quality throughout the entire drinking water supply network. This study used four planar laser-induced fluorescence (PLIF) units for ... -
Queue Length Estimation on Urban Signalized Intersection Combining Automatic Vehicle Identification and Vehicle Trajectory Data
(American Society of Civil Engineers, 2025)Queue length is one of the indicators of the state of traffic and is often used to measure the operational state of signalized intersections. Many studies have proposed estimating queue length from vehicle trajectory data ... -
Question-Answering System Powered by Knowledge Graph and Generative Pretrained Transformer to Support Risk Identification in Tunnel Projects
(American Society of Civil Engineers, 2025)Risk identification is fundamental to effective risk management in any construction project. It is especially true for tunnel projects where technicality and complexity increase the risks, uncertainties, and challenges of ... -
Quantitative Evaluation of Microtexture Frictional Properties of Aggregates and Reclaimed Asphalt Pavement
(American Society of Civil Engineers, 2024)The frictional properties of aggregates play a significant role in determining pavement skid resistance. To preserve natural aggregates, reclaimed asphalt pavement (RAP) has been widely used for decades. However, its use ... -
Anisotropic Strength Identification of Sandy Cobble Soil Using Multiscale Limit Analysis
(American Society of Civil Engineers, 2025)Sandy cobble soil is a composite made of soil matrix and cobbles, and the estimation of its shear strength always requires expensive large-scale experiments. The strength of the sandy cobble soil exhibits macroscopic ... -
Quantitative Assessment and Optimized Utilization of Soundless Cracking Demolition Agent for Fragmentations of Basalt Fiber–Reinforced Concrete
(American Society of Civil Engineers, 2025)The soundless cracking demolition agent (SCDA) technique provides an environmentally friendly approach for demolishing brittle structures. An integration of experimental and numerical approaches was adopted to explore an ... -
Quantitative Analysis of Risk Influential Factors of Evacuation Accidents for Passenger Ships
(American Society of Civil Engineers, 2025)With the increasing use of passenger ships in passenger transport and tourism sighting, the risk of evacuation accidents is higher. To prevent such accidents and reduce casualties, a quantitative analysis method for ... -
Quantifying Railway Ballast Degradation through Repeated Large-Scale Direct Shear Tests and Three-Dimensional Morphological Analysis
(American Society of Civil Engineers, 2025)To investigate the mechanism and manifestation of ballast spoilage, this study introduces a novel approach using a repeated large-scale direct shear test (involving multiple large-scale direct shear tests on the same batch ... -
Quantifying Project Uncertainties: Leveraging Historical Bid and Change Order Data for Automated Detection of Cost and Schedule Impacts in New Projects
