Using the fiber spacing theories, the paper analyzed the strengthening mechanism of plant root and set up a model to predict the contribution of root to the shear strength of composite soil, which had the same style as the contribution of internal steel in reinforced concrete to shear reinforcement. The paper put forward that, the contribution of root to the shear strength of composite soil was mainly decided by the average tensile strength, direction of root, the area ratio of root or average spacing of root, and analyzed main impact factors, and finally verified the strengthening model of plant root in an instance project.
