Abstract： To address the eficiency evaluation of organizational management in unmanned construction of driland-blast tunnels，an evaluation system based on the super-efficiency Slack-Based Measure （SBM） model with undesirable outputs was constructed. Taking a tunnel under construction in the Xizang Autonomous Region as a case study，an evaluation index system comprising four input indicators and four output indicators was established， wherein the overbreak volume was treated as an undesirable output.The evaluation of 30 construction cyclesrevealed that the average efficiency value was O.988，with 66.67% of the cycles being DEA-efficient. The sub-process scheduling time and advance distance per cycle were identified as the most critical factors influencing the organizational efciency.Furthermore，construction cycles at diferent efficiency levels exhibited significant sensitivity stratification characteristics，indicating the presenceofa diminishing marginal effect in eficiency improvement.
