A Study on the Stability of Tailings Pond Based on Plastic Displacement and Safety Factor

Yadong Li — 2026-05-28

The displacement deformation of tailings ponds serves as important early warning indicators for its instability, and accurately identifying plastic displacement is crucial for establishing a safety early warning system for tailings ponds. This study proposes a method for identifying plastic displacement in tailings ponds, systematically analyzes the variation pattern of plastic displacement with applied loads, and establishes the relationship between plastic displacement and the safety factor. The results indicate that the dam body is in the elastic deformation stage during the initial loading period. As the load increases, it enters the plastic deformation stage, and upon reaching the breaking load, the plastic displacement increases sharply. The maximum plastic displacements are 55.986 mm, 49.009 mm, and 44.197 mm, occurring at the sliding arc of the dam body. Furthermore, the safety factor exhibits a nonlinear inverse relationship with plastic displacement: the lower the safety factor, the greater the plastic displacement. Particularly when the safety factor drops below 1, the plastic displacement increases dramatically, indicating imminent dam failure. Based on these findings, the study provides an early identification basis for the instability risk of tailings ponds and proposes a scheme for establishing an effective early warning system, which holds significant engineering application value.

Study on the Evaluation Method of Highway Tunnel Service Performance Based on the Analytic Hierarchy Process

Zhihong Zhou — 2026-06-11

Current specifications mainly evaluate the highway tunnel service performance in the operation period from the integrity or defect status of tunnel engineering structures and mechanical and electrical facilities, yet fail to fully take into account the durability of tunnel structures or facilities, traffic flow smoothness, riding comfort and other performance dimensions. Therefore, by adopting research methods including literature research, theoretical analysis and expert investigation, an evaluation indicator system for the highway tunnel service performance was established based on the Analytic Hierarchy Process (AHP), and calculation models for each indicator were constructed, thus ultimately realizing the quantitative evaluation of tunnel service performance. Finally, based on the data of 33 ordinary highway tunnels in Shandong Province in 2025, the service performance scores of these tunnels were calculated, and the tunnels were ranked by maintenance priority according to the calculation results. This research provides an important basis for the maintenance decision-making of ordinary highway tunnels in Shandong Province.

Zizun Liu — 2026-06-11

Against the backdrop of the construction industry’s transition towards industrialization and intelligence, prefabricated buildings have emerged as a core direction for promoting high-quality development in the sector. BIM (Building Information Modeling) technology, as a pivotal tool for lifecycle management in prefabricated buildings, directly influences the effectiveness of professional talent cultivation. The blended teaching model, which integrates the advantages of online and offline instruction, breaks through the temporal and spatial constraints of traditional teaching. Meanwhile, the rapid development of AIGC (Artificial Intelligence Generated Content) technology offers new solutions to address challenges in BIM teaching for prefabricated buildings, such as insufficient practical scenarios, lack of personalized guidance, and outdated teaching resources. This paper analyzes the current status and pain points of BIM teaching for prefabricated buildings under the blended teaching model and proposes targeted application strategies and safeguard measures. The aim is to optimize the BIM teaching process, enhance teaching efficiency and quality, cultivate compound talents in BIM for prefabricated buildings who meet industry demands, and provide theoretical references and practical insights for the reform of teaching in the prefabricated building field.

Building Carbon Emission Accounting and Whole Life Cycle Decarbonization Pathways for Green Buildings

Jianwei Zhao — 2026-06-11

As one of the world’s primary sources of carbon emissions, the building sector’s decarbonization progress directly affects the realization of “dual carbon” goals. Based on life cycle theory, this paper systematically analyzes the technical logic and limitations of carbon emission accounting methods for buildings, and elaborates on innovative pathways for green building decarbonization technologies, including passive design, active energy systems, and BIM-based digitalization. The Technology Acceptance Model (TAM) and a tripartite evolutionary game framework are introduced to analyze the barriers and driving mechanisms for technology diffusion from a socio-technical perspective. Using practical cases from China Construction Science and Technology Group Co., Ltd. (CSCSTC), the paper quantifies emission reduction performance. Finally, a coordinated implementation framework integrating policy regulation, technological innovation, and market incentives is proposed. Results show that combining Life Cycle Assessment (LCA) with the emission factor method can improve accounting accuracy by over 30%; integrating passive design and renewable energy technologies reduces building energy consumption by 50–64%; and scaled application of the “Photovoltaics + Energy storage + Direct current + Flexibility” (PEDF) system achieves renewable energy self-consumption rates above 80%. Furthermore, modular construction reduces carbon emissions from the construction phase by 30%, while green financial instruments such as preferential loans can raise project internal rates of return (IRR) by approximately 2–3 percentage points. This study provides theoretical support and practical guidance for low-carbon transition in the building industry.

Research on Traffic Volume Transfer Forecasting for Expressway Reconstruction and Expansion under the Condition of Regional Road Network Linkage

Ruyi Chen — 2026-06-11

Against the backdrop of the concurrent advancement of China’s expressway network development and large-scale reconstruction and expansion projects, the reconstruction and expansion of a single road section can trigger a redistribution of the overall traffic flow within the regional road network, with significant characteristics of traffic volume transfer across routes, corridors, and regions. Traditional traffic volume analysis methods, which focus on individual road sections, struggle to meet the practical demands of regional road network linkage, multi-path competition, and dynamic traffic organization. To scientifically grasp the traffic transfer patterns within the road network during reconstruction and expansion and ensure the safety and efficiency of road network operations during construction, this paper adopts a perspective of regional road network linkage to systematically analyze the internal mechanisms and spatiotemporal distribution characteristics of traffic volume transfer during expressway reconstruction and expansion. Furthermore, it proposes a traffic volume transfer forecasting and analysis system suitable for reconstruction and expansion scenarios. Through this analysis, the paper aims to provide theoretical support and practical references for formulating traffic assurance plans for expressway reconstruction and expansion projects, optimizing the allocation of regional road network resources, and preventing and controlling traffic operation risks. This research holds significant importance for enhancing the service level of the road network during expressway reconstruction and expansion.
