SURFACE MODEL OF STONE WALL AND ADHESION EFFECT OF VINE

This paper presents a simple model that is aimed to be utilized as a measurement for predicting a surface stability of stone wall and also to evaluate an adhesion effect of vine developing along the surface of stone wall. The stability model of stone blocks pile is constructed based on Coulomb friction that acts between contacted blocks. Also, in this paper, pulling out test applied for trunk of vein is contained. It is expected that this amount of strength is affected by adhesion of trunks as well as the morphological properties of vine. This study leads to the new model for measuring the stability of geo-synthetic blocks pile. Parametric study based on the presented model indicates that the slope of surface of blocks pile have more effect on the stability comparing with the slant of wall surface itself. Furthermore, although the equivalent cohesion derived from the adhesion of vine remarkably affects the stability of sliding, it is concluded that it doesn’t affect the stability of rotation.
