基于集对分析的地铁隧道施工塌方风险评价模式研究

Research on Landslide Risk Assessment Model about Subway Tunneling Based on Set Pair Analysis

地铁隧道施工塌方问题一直是影响工程建设的主要问题,风险评价是衡量塌方风险大小的手段,现有的风险评价方法普遍存在方法简单、主观性强、评价结果可靠性不高等问题,由于塌方风险具有较多的不确定性,且指标之间具有关联性.文中基于集对分析理论构建集对评价法,并应用到地铁隧道施工塌方风险评价中,该法考虑了塌方中的不确定因素和指标之间的关联性等问题,使得评价结果更为可靠.

The tunnel collapse problem has always been the major problem of construction projects. Risk assessment is a means to measure the degree of landslide risk. At present, the risk assessment method is generally the existence of deficiencies, as method is simple, subjective is strong, reliability of assessment result is poor, and so on. Because landslide risk has more uncertainty, and indexs exist the interrelation. This article builds set pair analysis method based on the theory of set analysis, and is applied to landslide risk assessment, which considers uncertainties of landslide, the interrelation of indicators, to the results of assessment make more reliable, which provides theoretical references to prevent or reduce the landslides risk of tunneling.
