摘要：
In the hazard assessment of debris flows, the determination of weights of assessment indices is both important and difficult. Base on the difficulty in defining weight values, the catastrophe theory is used in the hazard assessment of debris flows, and the advantage of catastrophe theory in the multi-rule assessment is used to avoid the subjectivity of artificial weights. The proposed method is conducive to calculation and does not necessarily define the weight of evaluation indices so that the influence of subjective factors on assessment can be minimized. The assessment results indicate that new assessment method is reasonable and feasible, and it provides a new idea for hazard assessment of debris flows.
