地下空间安全评价方法综述

RESEARCH SUMMARY OF SATETY ASSESSMENT METHODS OF UNDERGROUND SPACE

针对地下空间安全评价方法的的研究现状,本文综述了地下空间安全性影响指标、评价对象、安全评价方法的评价体系,并提出安全评价的难点及发展趋势。介于地下空间复杂性的特点,影响安全性指标复杂多样,评价对象分单灾种和多灾种,评价方法也不是单一确定。比较不同评价对象及使用的评价方法。介绍主要的安全评价方法,包括层次分析法、模糊综合评价、TOPSIS法、灰色关联度分析、神经网络、仿真技术,并对各评价方法进行优缺点对比。此外研究了安全评价难点和热点,对未来的发展趋势做预测。地下空间安全评价的结果具有一定的说服力,但不能唯一确定地下空间安全性。

The paper reviewed the evaluation system of underground space security impact indicators,evaluation object and safety evaluation method for research status of safety evaluation method,and proposed the difficulties and trends of the methods. Due to the complexity of underground space,the security indicators were complex and diverse,evaluation objects were divided into single-hazard and multi-hazard,the method of evaluation was not a single determined. It compared different evaluation objects and their methods. It described the main safety assessment methods,including AHP,fuzzy comprehensive evaluation,TOPSIS method,gray correlation analysis,neural networks,simulation technology,and compared the advantages and disadvantages of each evaluation method. In addition,the research studied the difficulty and hot of safety assessment,and forecasted development trend for the future. The results of safety assessment of underground space had some persuasion,but not uniquely determined the safety of underground space.
