Innovative Simulation Model Enhances Construction Efficiency and Safety in Arch Dam Projects

The construction industry is embracing new technologies, with innovative simulation models helping to address critical challenges faced during the construction of arch dams. Efforts are being made to mitigate issues stemming from mechanical spatial–temporal conflict, which can negatively affect the quality, safety, and scheduling of projects.

Spatial-temporal conflict occurs when different labor crews, assigned to complete tasks simultaneously, are forced to work within the same limited area. This overlap often leads to physical collisions and operational inefficiencies, which can derail project timelines and increase safety risks. Understanding and simulating these conflicts is now deemed essential for optimizing construction management and organization.

Focus on Baihetan Arch Dam

The recent study concentrated on the pouring construction process of the Baihetan Arch Dam in China, analyzing the levels and effects of spatial-temporal conflicts throughout the project’s lifecycle. A newly proposed algorithm has been developed to quantify these conflicts, assessing them based on safety, potential efficiency loss, and the risks posed by potential collisions.

The constructed simulation framework encompasses various objectives including operational cycles, resource allocation methods, and fundamental modeling assumptions related to construction machinery. Advanced visual simulation systems enable professionals to compile and analyze the data on conflicts more effectively.

Simulation Results

Data from the simulations reveal that spatial-temporal conflicts frequently occur during the pouring process of arch dams. These conflicts not only present safety hazards but also contribute to declines in overall efficiency. As a result, strategic planning for unloading points and careful trajectory settings for construction machinery have been identified as key measures to reduce risks associated with these conflicts.

The arch dam pouring process typically employs a layered-block method, where numerous independent units are formed by countless pouring blocks. It has been established that the safety and efficiency of the overall construction effort are closely tied to the specific conditions of each pouring block.

Quantifying Risks

The study outlines various quantifiable metrics such as the rates of physical collision accidents, security risks, and efficiency loss at various stages of the construction process. These insights provide a solid theoretical framework for preemptive adjustments and risk assessments during the pouring activities.

Several factors influencing these spatial-temporal conflicts were identified, including the size of machinery, the chosen construction methodologies, operational speeds, and the trajectories of machinery in use. The developed simulation model adeptly showcases the complex and often random nature of construction procedures inherent to the pouring phase.

Significance of the Findings

The case study of the Baihetan Hydropower Station underscores the vital necessity for efficient management practices in construction operations. The findings of this study have broader implications, offering valuable insights that could enhance the safety and effectiveness not only in arch dam projects but in similar construction endeavors around the globe.

In conclusion, employing an innovative simulation model for analyzing and managing spatial-temporal conflicts is proving to be a game-changer in the construction sector. By adopting these new technological strategies, the industry can navigate the complexities of construction, leading to improved safety outcomes and higher efficiency in project delivery.
