| 摘 要： | 首先确定了软土地区土压式盾构掘进施工主要风险,针对掘进施工风险的随机性与模糊性特点,提出采用模糊综合评价模型对其进行研究,其中采用层次分析法计算各风险事件的相对权重,并采用梯形隶属函数来计算各风险事件对风险水平的隶属度,将风险事件的权重与风险事件对风险水平的隶属度进行模糊综合运算,可得出掘进施工的总体风险水平,最后通过算例进行实证研究,评价结果基本能反映实际情况。

| Abstract: | In light of the randomness and fuzzy characteristic of EPBS ‘constructing risk, a fuzzy synthetic evaluation model is brought forward to study it; in the model, the risk’s weight is calculated by the analytic hierarchy process; and the membership degree to the risk level is calculated by trapezoidal membership function; then the total risk can be calculated by fuzzy calculating the weight and the membership degree; at last, a case study is done on Metro 8 in Shanghai which is constructed by EPBS; the consequence is coincidence with the reality. |
