摘要

根据工程风险评价的基木原理,针对隧道工程风险评价的特点,提出了一种可以对隧道工程地震风险进行定级评估的方法,采用定性和定量相结合的方法,通过确定地震发生的概率和地震在隧道工程发生所产生的后果,给隧道工程地震风险定级,根据风险定级对隧道工程地震风险进行评价,并以一隧道工程为例,阐述了R=P×C法的具体应用。
Based on the keystone of the engineering risks assessment,the characteristics of the risk analysis in the tunnel engineering are studied.The method of how to assess grade for the risks of tunnel engineering under the condition of earthquake is proposed.The main principle of the method is to combine the qualification with quantification,the probability of the earthquakes occurred and the destruct results of the earthquake in tunnel engineering are decided.The level assessment of risks are made by the probability and the destruct results,the risk evaluations are made by the level assessment of risks.A case is used to expatiate the apply of the R=P×C method.
