A Safety Resilience Evaluation Framework for Temporary Works on Construction Sites Under Typhoon Conditions

Considering the diverse structures, short service periods, dynamic site layouts, and vulnerability of temporary works to strong winds and heavy rainfall, a safety resilience evaluation framework is proposed to address typhoon-related risks. Drawing on resilience engineering theory and the typhoon disaster process, safety resilience is divided into five dimensions with 21 indicators: pre-disaster prevention, disturbance resistance, emergency response, post-disaster recovery, and learning and adaptive capacity. Subjective and objective weights are determined using the G1 method and entropy weight method (EWM), respectively, followed by integration through quadratic optimization. TOPSIS is then used to evaluate resilience. Risk early warning, hazard identification and inspection, emergency resource preparedness, personnel evacuation, and response timeliness receive relatively high weights. The case project achieves a relative closeness coefficient of 0.678, corresponding to Level II resilience. Sensitivity analyses of weights, indicator scores, and indicator structures show generally consistent evaluation levels, indicating classification stability. The framework supports resilience evaluation and vulnerability identification of temporary works under typhoon conditions.
