QUANTITATIVE CONSIDERATION OF TREE-SHRUB VEGETATION IN SLOPE-STABILITY ANALYSIS

摘要

A procedure is presented for consideration of the reinforcing functions of the root system of trees and shrubs when analyzing their capacity to stabilize slide-prone slopes. The resistance offered by the roots can be accounted for by an artificial increase in the specific cohesion of the soil in the upper layer that they have penetrated (thickness of 2-0.5 m).
