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

The construction of arch dams is witnessing a breakthrough in efficiency and safety thanks to an innovative simulation model. This advancement addresses the common problem of mechanical spatial-temporal conflict that can lead to serious quality, safety, and scheduling issues during the pouring process. By examining these conflicts, the model promises to optimize organizational and management processes on site, particularly in complex projects like the Baihetan arch dam.

Understanding Spatial-Temporal Conflict

Spatial-temporal conflict occurs when different labor crews, assigned to simultaneous activities, share the same workspace. This overlap not only increases the risk of physical collisions but also hinders overall efficiency. To combat this, construction process simulation and thorough analysis of these conflicts are becoming increasingly critical within the industry.

Focus on the Baihetan Arch Dam

The simulation model places particular emphasis on the pouring process of the Baihetan arch dam, a significant project in hydropower development. It offers an in-depth analysis of the various levels and impacts of spatial-temporal conflicts during construction. One of the notable advancements of this study is a proposed quantification algorithm that categorizes these conflicts based on factors such as safety risks, efficiency loss, and collision probabilities.

Construction Process Simulation Framework

The simulation framework integrates several key elements, including objectives, operational cycles, and resource allocation mechanisms. Core modeling assumptions regarding construction machinery further enhance the reliability of the simulation results. The visual simulation systems developed as part of this framework allow for the effective integration and analysis of conflict information, streamlining the decision-making process on-site.

Simulation Results and Findings

safety risks and a decline in operational efficiency. To tackle these issues, the study recommends effective unloading point planning and strategic trajectory settings for construction machinery. This approach is vital for mitigating the risks associated with having multiple crews operating in close proximity.

Efficiency and Safety Correlation

The pouring process in arch dam construction typically employs a layered-block method, which consists of numerous independent units formed by countless pouring blocks. The safety and efficiency of a dam construction project are closely linked to the operational conditions of each block. Notably, the physical collision accident rate, security risk rate, and efficiency loss rate are now quantifiable at any given time during the construction phase.

Theoretical Basis for Risk Management

This study not only sheds light on the nature of construction conflicts but also provides a theoretical foundation for early warning systems and adjustments to construction risk assessments during the pouring process. Factors influencing spatial-temporal conflicts include machinery size, construction methodology, operational speed, and the running trajectory of equipment. Understanding these variables is crucial for effective risk management.

Insights for Future Construction Projects

The developed simulation model reveals the intricacies and unpredictable nature of construction procedures evident in the pouring process. The Baihetan Hydropower Station serves as a pertinent case study, highlighting the importance of refined management and approaches in construction operations. The insights derived from this analysis promise significant enhancements in the safety and efficiency of construction processes in similar arch dam projects around the globe.

Conclusion

With the introduction of this innovative simulation model, the construction industry is poised for an evolution in how projects are managed, especially in complex environments like arch dam construction. By addressing the challenges posed by spatial-temporal conflicts, this model not only ensures better safety standards but also optimizes resource use and enhances overall project success rates.
