LEC风险评价法的改进及其在隧道施工中的应用

Improvement of LEC Tisk Analysis Method and Its Application in Tunnel Construction

作为目前应用最为广泛的风险分析方法,LEC风险评价方法可以为相关工作提供准确的风险评估。但由于其对于风险发生概率的估算过于主观,在实际应用中存在一定的局限,需要进行相应的改进。基于LEC评价法的基本概念,对该方法的缺陷加以分析,并提出相应的改进方法,最后结合某公路隧道施工,对改进后的LEC评价法的应用进行了评价。

As the most widely used method of risk analysis, the risk assessment method LEC can provide an accurate assessment of the risk associated with the work. However, because of the subjective of this risk value for the probability, there are certain problems in practice which need to he improved accordingly. This paper focuses on the main concept of LEC to analyze its defects and puts forward considering solving measures, finally evaluates the application of LEC combing with a highway tunnel construction case.
