Title:
SLOPE MONITORING SYSTEM, SLOPE MONITORING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/176836
Kind Code:
A1
Abstract:
In order to make it possible to grasp, in a stepwise manner, a safety factor and a degree of danger that change in accordance with the moisture content in soil and to enable the issuing of warnings and evacuation orders in stages, this slope monitoring system 1 comprises: a measurement unit 11 that measures soil parameters in association with a moisture content regarding a material layer constituting a slope to be monitored; a modeling unit 12 that generates a model formula on the basis of the measured soil parameters and moisture content; an optimal state moisture content estimation unit 13 that estimates an optimal state moisture content at which a maximum safety factor is achieved; a moisture meter 15 that measures the current moisture content in the slope to be monitored; a current safety factor calculation unit 16 that calculates a safety factor using the soil parameters estimated from the current moisture content; an optimal state safety factor calculation unit 17 that calculates a safety factor using soil parameters estimated from the optimal state moisture content; and a danger degree output unit 18 that outputs a current danger degree level in which the optimal state is used as a reference.
