Research on the Contribution-Ratio Predication Method Applied to the Predication and Warning of the Risk of Roadbed Geological Hazards
The predictable evaluation of the risk of roadbed geological hazards depends largely on the reliability of the fundamental information and the rationality of the mathematical model. As all the factors of the geological environment at different regions are different in the quality, the same index is likely to attach to the different fatalness grade at the different regions. Therefore, the application of the classical mathematical model to dividing the uniform standards for measuring still belongs to one of the challenging frontiers in the current international earth science field. In this paper we attempt to establish the mathematical model of contribution-ratio predication method in the predictable evaluation of the risk of roadbed geological hazards to determine the critical rainfall in which geological hazards take place, hoping to provide the theory reference for the predication and warning problems of the risk of roadbed geological hazards.
