METHOD FOR CALCULATING SURFACE SOIL DISPLACEMENT OF SLOPE AND DISASTER PREVENTION INFORMATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To allow a general inhabitant to predict disruption of a slope at the back of home.;SOLUTION: A means for determining surface earth displacement ε by determining tectonic coefficient X and hydrological coefficient Y based on two past rainfall histories by use of a coefficient model represented by expression 1: K={(sectional shape coefficient α×tan θ)×(loose layer thickness D×loose coefficient δ×X+planar shape coefficient β×rainfall P×Y)-(tree kind coefficient λ×tree age coefficient μ+friction coefficient τ of soil mass)}, wherein θ is the gradient of a slope, forming a surface soil displacement calculation model, and squaring instability K of the slope to future rainfall is provided through the Internet, so that the general inhabitant can estimate the surface soil displacement ε of the slope at the back of home for rainfall information.;COPYRIGHT: (C)2010,JPO&INPIT
