Abstract
In order to promote efficiency in slope disaster countermeasure projects, it is important to grasp the hazardous nature of each slope and plan appropriate countermeasure work. In this research, we utilize the support vector machine math ematical technique to try to determine countermeasure work selection flows for hazardous slopes. First of all geographical and geol ogical predisposition and past disaster history is used to determine slope hazard level and need for countermeasure work, and slope hazard evaluation standards are set for each construction type. These evaluation standards are used to calculate the current degree of slope hazard and calculate the slope hazard if new countermeasure work is added. From this it is possible to evaluate what kind of countermeasure work would be most effective for each slope.
We conducted a site investigation of locations judged as requiring countermeasures by the set countermeasure work selection flow. The results showed that, the selection of countermeasure work was consistent with knowledge of engineers gained from the local conditions, and we believe the fruits of our research will be effective techniques in consider ations of disaster prevention project plans.
