“…Verma [14] proposed a generalized weighted BM and developed a MADM method for IFS data. Gu et al [15] proposed a TOPSIS approach to evaluate the risk index of landslide hazards in Shiwangmiao city under IFS information. However, in many real-life problems, the aggregate of grades of membership and non-membership of element possibly bigger than 1, instead their square sum is either less than or equal to 1.…”

“…With the development of science and technology and the progress of human society, the urbanization is accelerated gradually [2], the human demand for resources is becoming more extensive, and the destruction of environment is obvious increasingly, so the geological hazards occur frequently. In particular, in mountainous areas, the occurrence of debris ow hazards has seriously endangered the life and property safety of the people [3].…”

The occurrence of debris flow hazards has great destructive effects on the life and property safety of the people. Many factors control its occurrence. The intuitionistic fuzzy sets-TOPSIS model is introduced to assess the risk level of debris flow in the Duba river watershed at first; secondly, the decisive matrix of the intuitionistic fuzzy sets is established, and the index weight coefficients are determined by using the entropy weight method, and then the weighed decisive matrix is obtained. Finally, the degree of membership at different levels is calculated. The risk level corresponding to the maximum degree of membership is regarded as the final assessment level. The conclusions are drawn, estimating that the risk level of debris flow hazards in the Duba river watershed based on the intuitionistic fuzzy sets-TOPSIS model is feasible when its results are compared with the actual investigation and Liu X.L model, and the model not only can reflect the risk level of debris flow hazards accurately, but also further determines the risk ranking of debris flow in four different gullies, so that it can provide a new method and thoughts to estimate the risk level of debris flow hazards in the future.

“…Many factors a ect the stability of surrounding rocks in reality [1,2], for example, the construction level, timbering opportunity, and the geometric deformation of cross-section [3,4]. In essence, these factors are relevant to the quality of surrounding rocks [5,6], so the quality of surrounding rocks during the construction process of the tunnel is adopted to assess the stability of the tunnel. Moreover, it is also used to select the engineering structure parameters and evaluate the economic bene t [7].…”

The quality assessment of surrounding rocks has tremendous influences on engineering construction, so its investigation is significant. The uniaxial compressive strength of rocks σ c , the integrity coefficients of rock mass K V , the conditions of the structural plane S S , the seepage amount of groundwater W , and the intersection angle θ between the axis line and structural plane are selected as the quality assessment index of surrounding rocks at first. Then, the entropy weight-variable fuzzy sets model is introduced. Second, the relative membership degree matrix about the variable fuzzy sets is established, and the weight coefficients are determined based on the entropy weight method. Finally, the fracture behavior level of surrounding rocks is determined using the mean ranking feature value. The conclusions demonstrate that the results obtained based on the variable fuzzy sets method are consistent with the current specification; its accuracy arrives at 80%. Compared with the traditional way, its assessment process has higher reliability and efficiency. So, it could provide a new alternate way to assess the risk level in civil engineering accurately.
