• Estimation of Reinforced Shear Resistance of Rooted Soil by Pull-out Resistance of the Roots

抄録

Estimating method for effect of tree root on a slope stability wasinvestigated. Large scale (30×30×30 cm) direct shear tests for rooted soil and pull-out testswere made using same shear apparatus and giving test conditions. Comparing those testresults, a new model that can infer the reinforced shear strength of roots from the pull-outstrength was developed. Simulated reinforced strengths by the model could coincide thoseobtained by the shear tests very well. Pull-out test is considerably easy and practical even inforest fields. The pull-out strength reflects influences of slope conditions and intact rootmorphology. So, it gives extremely worth information in a field. The model should beimproved to apply actual forest slope stability problems.
