摘要
城市地铁盾构隧道施工常因出现各种事故而未能达到预期目标,即存在风险性。为了研究地铁盾构隧道施工中各种事故发生的概率以及事故造成的损失,采用模糊层次分析法,对杭州某地铁盾构隧道施工进行风险识别和风险估计,并在此基础上采用模糊综合评判法进行风险评价,得出该地铁盾构隧道施工的风险等级。该法不需对判断矩阵进行一致性检验,并能够保证在度量相对准确的基础上,使计算过程得到简化。文章最后对评判结果进行有效性验证,增加了可信度。本次实例风险分析可为同类型工程项目提供借鉴。
There are many accidents during construction of shield tunneling engineering in urban area. In order to study the occurrence probability of the accidents and their losses, This paper conducts research on risk identifica tion and risk estimatiou for a subway construction process in Hangzhou with the method of Fuzzy Comprehensive Eval uation. Based on the research, a risk level of the subway construction is given according to risk evaluation by Fuzzy Comprehensive Judgement. Since there is no need to check the consistency of the judging matrix, the method used can simplify the calculation process on the basis of relatively accurate measurement. In the end, the paper attests the validity of the judging result, which increases the reliability of the result. The research can provide reference to simi lar projects.
