摘要
我国属于地震灾害多发国家,铁路隧道受震害影响大,造成的损失较为严重,如何定量快速评估震害损失显得十分重要。文章介绍了模糊层次分析法和10/10-18/2分数标度法权重值计算法及其结果的计算一致性比例CR验证方法,并建立了铁路隧道结构构造的轨道部分、主体结构和附属建筑物等常见震害的层次结构模型,采用10/10-18/2分数标度法对铁路隧道结构构造及常见震害的权重值进行计算,并对结果进行了计算一致性比例CR验证。结果表明:在对铁路隧道震后损失定量评估研究时,在建立结构构造及常见震害层次模型的基础之上,采用10/10-18/2分数标度法计算权重值较为合理、准确。该研究可以作为铁路隧道震害程度等级划分及经济损失的依据,可实现对单座铁路隧道损失情况的定量评估。
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 resuits 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.
