METHOD FOR EVALUATING EARTHQUAKE RISK OF ROAD SLOPE

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating the earthquake risk of road slopes and capable of approximately predicting sections possibly to be stricken by a disaster and heightening a prediction rate of the striking of a disaster and the not-striking of the disaster as a whole.;SOLUTION: In the method for evaluating the risk of the occurrence of disasters at the occurrence of an earthquake, disaster risks are determined on the basis of determination values computed on the basis of scores of a disaster-prevention record created on the basis of general inspections of road disaster prevention on heavy rainfall at an evaluation point for the evaluation of risks; a confirmation frequency of the execution of the general inspections of road disaster prevention at the evaluation point; oscillation values indicting the oscillation of strata at the evaluation point; and an average tilt angle of a slope at the evaluation point. It is possible to determine disaster risks based on seismic vibrations and topological characteristics through the use of evaluations by heavy rainfall disasters. Since it is possible to evaluate disaster risks suitable for actual conditions of the evaluation point, it is possible to appropriately predict sections possibly to be stricken by a disaster and also heighten a prediction rate of the striking of a disaster and the not-striking of the disaster as a whole.;COPYRIGHT: (C)2010,JPO&INPIT
