This article is based on the summary of the current situation of disaster prevention and rescue design in railway tunnels,combined with the analysis of the characteristics of railway tunnel disaster prevention and rescue construction organization,and the analysis of the current railway tunnel disaster prevention and rescue quota and cost calculation method.The adaptability of disaster prevention and rescue engineering quota is summarized,and typical cases are selected for measurement and verification.The conclusion indicates that the smoke exhaust ducts for disaster prevention and rescue in railway tunnels have complex spatial distribution,multiple working faces,and low turnover efficiency of construction equipment.The current quota and billing method may have insufficient costs,and there may be significant discrepancies in the consumption of personnel,materials,and machinery measured on site compared to the quota.
