Comprehensive safety evaluation method of expressway tunnel group
Wei Deng · Journal of Chang'an University · 2012
Through analyzing the expressway tunnel group operation safety features and evaluation theory demand,a comprehensive safety evaluation method with cloud model and matter-element analysis theory was proposed.This method can use matter-element model to establish the corresponding relations between evaluation objects and evaluation indexes for realizing the information feedback of evaluation system,and also can use cloud model to set up the uncertainty conversions between numerical value concept and natural language for realizing the uncertainty evaluation of language evaluation indexes.Finally,the method was verified by a project example of Xi'an—Hanzhong expressway tunnel group.The result show that this method can take the extension transformation into the evaluation index system,and give easy way to develop comprehensive safety evaluation system software by computer programming for engineering application.
