A Risk Assessment Method for Metro Shield Tunnel Construction Based on Interval Number
https://orcid.org/0000-0003-1309-0343
Abstract In recent years, metro construction is flourishing in China. In the construction process of the metro shield tunnel, there are various complex potential risk factors fraught with many uncertainties. Therefore, it is crucial to conduct a risk assessment on urban metro shield construction. To improve the accuracy of the risk assessment results of metro construction projects, a risk assessment model based on interval numbers is proposed from the perspective of uncertainty. The experts’ evaluation information is represented by the interval number, and then the operation rule and membership function of the interval number is used to calculate the risk level of each potential risk factor. Afterward, the weight of each evaluation index is calculated based on the interval number and the C-OWA operator. From the bottom of the evaluation system, the layer-by-layer operation is carried out to determine the risk level of the assessment index of each layer, and the risk grade is divided according to the risk matrix. Taking a section of the shield tunnel of Shenzhen Metro Line 12 as an example, the proposed method is used to evaluate the construction risk, and the potential risk factors that require the implementation of risk prevention measures in the project are obtained. The calculation results show that the assessment model is reasonable and reliable, and has high stability.
