Optimization of electric concrete transport vehicle configuration for long-distance tunnel construction considering driving range: a case study

This study optimizes the configuration of Electric Concrete Transport Vehicles (ECTVs) for long-distance tunnel construction, focusing on the critical factors of driving range and reliability. A comprehensive model integrating tunnel length, terrain, construction schedules, vehicle load capacities, driving range, and reliability is developed. The study acknowledges limitations of traditional fuel-powered vehicles and proposes ECTVs as a sustainable and reliable alternative. The model is validated through a case study in a plateau region of Southwest China. Key findings show that the number of ECTVs required increases with excavation distance, seasonal variations significantly impact configuration, and balancing loading capacities with driving range and reliability is crucial for optimization. The study contributes a new approach to ECTV configuration by incorporating driving range and reliability into the model, offering practical guidance for construction managers to reduce costs, minimize delays, enhance efficiency, and improve reliability.
