摘要
The present invention relates to a technique for applying a simple disaster diffusion model to calculate the damage range of a natural disaster. In particular, in order to predict the damage risk due to a natural disaster on the road, a high level of engineering analysis is required for each point, but linear Since it is virtually difficult to interpret numerous dangerous points on a road, which is a structure in the form of a road, in order for a road manager to predict damage on the road and respond to it by referring to the disaster map, it is possible to intuitively judge the overall risk of the entire road. A volume balance approach as a simple model development model for estimating the extent and scale of natural disasters so that the cause of natural disasters that damage the road can be used as a means to evaluate the case where the damage causes damage by propagating down the road; Using the marginal topography method, empirical equations, and physical methods, it is possible to estimate and predict the extent and scale of disaster spread through the combination of heavy rain and steep slopes and debris flow. According to the present invention, not only the analysis of the cause of damage that causes damage to the road but also the damage caused by the expansion of the cause of the damage can be grasped, so that the actual risk of a disaster can be assessed. A preemptive response to In addition, it is possible to quickly identify road points with a high risk of disaster and execute the budget in the right place where detailed engineering investigation is required.
