The susceptibility assessment of debris flow hazards based on the game theory combination weighting-normal cloud model.

The susceptibility evaluation of debris flow has excellent significance for people's life and property safety. The game theory combination weighting-normal cloud model is applied to evaluate its susceptibility in the paper. Firstly, the length ratio of the supply segment (X1), the longitudinal slope of the main ditch (X2), the slope of the mountain (X3), watershed area (X4), the relative difference (X5), the vegetation coverage (X6), as well as the daily maximum rainfall (X7) are adopted as the assessment index; the game theory combination weighting-normal cloud model is introduced.

The risk assessment of rockburst intensity in the highway tunnel based on the variable fuzzy sets theory.

Rockbursts have important influences on construction safety, so the risk assessment of rockburst intensity has great significance. Firstly, the depth of the rockburst, the uniaxial compressive strength, the stress concentration coefficients, the brittleness coefficients, and the elastic energy index are selected as the evaluation index. Secondly, an assessment model is developed based on the fuzzy variable theory.
