摘要
可拓诊断方法是进行系统故障诊断的一种有效方法。为了提高地铁预警管理系统的应急能力,在充分考虑灾害后果延迟性和次生灾害发生性的前提下,选取地铁地下基坑工程施工事故中的常见警兆作为诊断目标,提出利用关联函数定量可控度的方法,建立可拓诊断模型,解决预案决策的优化问题,提高预案触发效率。最后以具体案例说明该方法的有效性。
Extension diagnosis is an effective method for i- dentifying system fault. With full consideration of the fol- low-up disaster effects and secondary disasters, the com- mon warning signs of subway foundation pit construction are selected as a diagnostic objective, the quantitative method of controllability by using correlation function val- ues is proposed, and the extension diagnostic model is es- tablished to optimize the emergency plans and improve the efficiency of the trigger system. Finally, the effectiveness of this method is verified through specific examoles.
