Abstract
To provide the basic information about slope stability analysis, tensile force and strength of tree roots like Pinus koraiensis, Larix leptolepis, Pinus densiflora, Quercus mongolica, and Alnus japonica were measured and analyzed. As a result, tensile force increases in forms of involution of root diameter. The mean tensile strength of roots like P. koraiensis, L. leptolepis, P. densiflora, A. japonica and Q. mongolica were calculated as $165.38kgf/cm^2$, $172.78kgf/cm^2$, $176.25kgf/cm^2$, $214.29kgf/cm^2$ and $224.19kgf/cm^2$ respectively. It was shown that tensile strength decreasing tendency as root diameter increases. Also, recalculated soil shear strength by tensile strength of the roots like P. koraiensis, L. leptolepis, P. densiflora, A. japonica and Q. mongolica were $0.099kgf/cm^2$, $0.104kgf/cm^2$, $0.106kgf/cm^2$, $0.129kgf/cm^2$ and $0.135kgf/cm^2$ respectively.
