A 3D Model Applied to Analyze the Mechanical Characteristic of Living Stump Slope with Different Tap Root Lengths

Although the current ecological engineering technology can reinforce shallow landslides, it cannot deep landslides. A new type of technology-living tree stump slope protection was developed, aiming at deficiency technology. For living stumps with different tap root lengths, mechanical properties and system were analyzed. The model based on finite element method, using Mohr-Coulomb failure criterion to consider plasticity soil. three-dimensional (3D) models lengths simulated by embedded beam elements. Changes in stress strain soil simulated. strength reduction method used here calculate safety factor slope. results showed that long taproots moved shear area deeper layers, increasing stability middle lower part mainly exerted its tensile played a positive role longer taproots, more stable Slope may be affected length, spatial morphology, layout Planting densely recommended engineering.
