In order to quantify the increased soil reinforcement by tensile strength of roots, tensile force and strength of Korean pine roots were measured and analyzed. Samples are selected along their live positioning depth and tested in root diameter from 1.4 to 12.7mm. Tensile force of Korean pine roots was proportional to the power of root diameter. Variance of tensile force was decreased as the soil depth was increased. The tensile strength of Korean pine roots were distributed from 30.17 kgf/§¨ to 457.67 kgf/§¨ by root diameter, and their average value was 111.00 kgf/§¨. The tensile strength of Korean pine roots was also decreased as soil depth was increased.
Key words: tree root, tensile force, tensile strength, Korean pine, slope stability
