Abstract

[With the rapid development of the construction of expressway and the increasing sense of environment protection of mankind at coastal areas in eastern China, the bio-engineering techniques for slope protection are becoming more and more important and being used widely in the construction of expressway. In this paper, several laboratory uniaxial tests with pull-out method were carried out to obtain the stress-strain relationship of single root of Eucalyptus saligna. In addition, mathematical model of experience for root tensile strength by regression analysis were obtained. The results of regression analysis show that the parabolic-curve model has good fitting precision and good generalization ability to describe the relationship of stress-strain. A uniform constitutive relation can be used to describe the stress-strain relationship of different root systems. It can be a conclusion that the pull-out method may determine the strength of tree root very well. Meanwhile, to attain the ultimate pull-out resistance of each single root and some engineering properties parameters. This kind root and its parameters do have a great impact on root mechanical properties, such as the maximum tensile strength and pull-out strengths. The plant is well suited to the large-scale demands for the practices in coastal areas.]
