Abstract Earthquakes occur frequently in China and often railway tunnels are much affected and seriously damaged as a result. The quantitative and rapid assessment of earthquake damage and loss is very important. The fuzzy analytic hierarchy process, weight value calculation of the 10/10-18/2 score scale method and the validation method for calculation consistency ratio CR are introduced. Hierarchical structure models of the rail, main structure and annex of the railway tunnel structure, which is often damaged by earthquakes, are established. The weight values of railway tunnel structures and common earthquake damages are calculated by the 10/10-18/2 score scale method, and the calculation consistency ratio CR is verified. The results show that it is more reasonable and accurate to calculate weight values with the 10/10-18/2 score scale method based on a hierarchical model of the tunnel structure and common earthquake damages for the quantitative assessment of railway tunnel damage and loss. The research results can be used as a basis for grading earthquake damage and economic loss assessment for railway tunnels, and it is feasible for the quantitative evaluation of damage to a single railway tunnel.
Abstract：
Earthquakes occur frequently in China and often railway tunnels are much affected and seriously damaged as a result. The quantitative and rapid assessment of earthquake damage and loss is very important. The fuzzy analytic hierarchy process, weight value calculation of the 10/10-18/2 score scale method and the validation method for calculation consistency ratio CR are introduced. Hierarchical structure models of the rail, main structure and annex of the railway tunnel structure, which is often damaged by earthquakes, are established. The weight values of railway tunnel structures and common earthquake damages are calculated by the 10/10-18/2 score scale method, and the calculation consistency ratio CR is verified. The results show that it is more reasonable and accurate to calculate weight values with the 10/10-18/2 score scale method based on a hierarchical model of the tunnel structure and common earthquake damages for the quantitative assessment of railway tunnel damage and loss. The research results can be used as a basis for grading earthquake damage and economic loss assessment for railway tunnels, and it is feasible for the quantitative evaluation of damage to a single railway tunnel.
