Assessment of slope construction risk uncertainty based on index importance ranking

Due to the complex geologic conditions in mountainous areas of China, the highways often encounter different risks induced by geological hazards during highway slope construction. In this paper, a new assessment system for highway construction risk is developed based on 11 parameters being classified into five categories. In addition, index importance ranking is proposed for a weighting coefficient distribution in the evaluation index system for the 11 parameters. This ranking substantially reduces subjectivity during the rating process. Feedback on this system has been received from many successful applications in 13 provinces of China. Therefore, the new system of slope construction risk uncertainty assessment based on index importance ranking has attracted wide attention in China.
