摘　　要：为了研究如何避免或者降低在隧道施工风险评估过程中的个体主观性影响,以某公路隧道为依托,分别采用传统的以地质资料和工程经验为主的评估法及基于地质雷达预报的评估法,利用模糊综合评价模型建立风险的权重及隶属度,对隧道施工风险进行对比性评估.将两种不同评估法所得评估结论与工程实际进行比较,结果表明:基于地质雷达预报的隧道施工风险评估法所得评估结论与工程实际更加吻合,评估结论能为施工作业提供有效的指导,达到了满足施工需求的目的.In order to study how to avoid or reduce the influence of individual subjectivity on risk evaluation of tunnel construction, on the basis of the data of a highway tunnel, a comparative evaluation was made for the risk of tunnel construction through two different ways, i. e. the traditional way that is mainly based on the geological data and the engineering experience and a new way that is based on the GPR （ground pen- etrating radar） geological forecast, and the risk＇s weight and the membership degree were established through the fuzzy comprehensive evaluation model. It is concluded from a comparison of the results from the above two different ways with the data of the real engineering of the tunnel that the evaluation conclu- sion produced based on GPR geological forecast is in better agreement with the engineering practical situation and can provide effective references for the construction work, and the construction needs can be met.
