SLOPE STABILITY EVALUATING METHOD AIMING AT PEELING-OFF TYPE FALLING STONE AND ROCK COLLAPSE

摘要

PROBLEM TO BE SOLVED: To provide a slope stability evaluating method aiming at a peeling-off type falling stone and rock collapse, having higher accuracy, and easily usable at a job site. SOLUTION: This slope stability evaluating method aims at the peeling-off type falling stone and the rock collapse. A slope of high risk is selected by a decisive factor of directly contributing to the occurrence of the peeling-off type falling stone and the rock collapse, and capable of immediately determining thereby that the slope is unstable among many factors of the peeling-off type falling stone and the rock collapse. Instability of the slope is evaluated in two stages of present instability and future instability. COPYRIGHT: (C)2003,JPO
