In complex multi-agent traffic environments, the accuracy and safety awareness of trajectory prediction directly affect the reliability of decision-making in autonomous driving systems. Existing approaches primarily focus on fitting historical motion patterns, while lacking effective mechanisms for modeling...

In tunnel engineering in cold regions, the bond interface between surrounding rock and concrete lining is prone to deterioration under the action of freeze-thaw cycles, which seriously threatens the safety of the project. Aiming at the deterioration of sandstone-concrete interface in cold regions, the...

This paper addresses the collaborative optimization problem of electric bus scheduling and charging by constructing a hybrid optimization model aimed at minimizing fleet size and maximizing vehicle utilization. An improved heuristic algorithm is employed to solve the model, and simulation experiments...

Traditional blasting techniques for rock and concrete demolition present environmental pollution and safety risks. Although soundless chemical demolition (SCD) is environmentally friendly, it faces efficiency bottlenecks such as long reaction times and poor low-temperature adaptability. This review aims...

To investigate the seepage evolution patterns of gravel-stabilized heavy clay slopes under dry-wet cycling conditions, a comparative study was conducted using large-scale indoor slope model tests and numerical simulations. Through five wet-dry cycles, the slope morphology, moisture content, and migration...

To address the unclear transverse seismic mechanism of column-type bent piers, this study investigates the advantages of three-column bent piers compared to single-column bent piers in terms of force distribution and plastic hinge zones. Numerical models were established using OpenSees to analyze the...

Challenges are faced in the repair of local deformation diseases of roadbeds in permafrost regions. Grouting roadbed repair materials with both permafrost engineering adaptability and cost-effectiveness need to be developed urgently. EPS lightweight compaction-filling thermal insulation grouting material...

The current approach of using ordinary Portland cement (OPC) and gypsum to enhance the sulfate attack resistance of high-belite calcium sulfoaluminate cement (HBCSA)-based materials remains inadequate, thereby limiting the application potential of this composite system in aggressive environments. To...

In the context of smart operation applications for general national and provincial trunk highways, prevalent challenges include inconsistent spatiotemporal references, fragmented and heterogeneous data, incompatible interface standards, and insufficient adaptability of smart applications. These issues...

In this study, the ABAQUS software was adopted to simulate and analyze the dynamic response and damage modes of bridge piers under the action of underwater explosion (UNDEX) loading A reasonable numerical model of bridge piers was established, and simulation tests were conducted under different impact...

Reactive Powder Concrete-Filled Steel Tube (RPCFST) columns combine high bearing capacity, good ductility, and excellent durability, and have attracted increasing attention in high-rise buildings, bridges, and structures exposed to severe service conditions. This paper reviews recent research on the...

Aiming at the problem that the influence of dynamic compaction foundation treatment on pile foundations and the safe construction distance in the wharf land area are mostly dependent on experience and difficult to accurately predict, this paper takes a large deep-water high-piled wharf project in Peru,...

To address the problems of insufficient milling accuracy, limited bottom surface smoothness, and unstable paving quality in conventional milling operations, this study focuses on 3D intelligent milling technology. The key procedures, including high-precision pavement information acquisition, point cloud...

To address slope instability and surface cracking along a certain expressway, a comprehensive reinforcement plan was developed that combines slope hazard clearance with combined anchor-spray and mesh-reinforced support, along with a comprehensive drainage system. To verify the practical effectiveness...

With the continuous expansion of railway construction in China and the increasing demand for seismic disaster prevention, the seismic performance of bridge piers has received growing attention. Self-centering piers can effectively mitigate seismic damage and control residual deformation, showing considerable...

This study investigates the effects of efficient crack resistant agent (HME®-V) with different dosage levels (0, 5%, 10%, 15%) on the fresh properties, mechanical properties and chloride ion penetration resistance of mass concrete. Hydration heat tests, XRD analysis and numerical simulation were carried...
