These are more obvious in super-large-diameter shield tunnel during construction. In the past, the results of risk assessment tended to be subjective since these reviews were mainly based on experience. A super-largediameter tunnel model is constructed by using calculation principle of FAHP-TOPSIS method based on quantitative analysis and objective weighting method to c… Show more
