Numerical Analysis of the Landslide Geohazards - Case Study with Gabions and Piles Solutions

The paper describes experiences from the stabilization of landslide slope. Evaluation of the landslide stability is one of the most important problems in geotechnical engineering because failure could cause catastrophic environmental. Analysis of the landslide slope was performed using FE method. It was possible to evaluate two alternative stabilizing techniques and to choose the optimal one. Methods of stabilization consisted in the use of gabions wall and stabilizing piles, as the supports of the slope. Although the gabions wall were able to stabilize the slope, increasing the number of gabions and their weight was not effective in increasing the safety factor. The proposed pile technique was more effective. The numerical analysis provided a good prospect to optimize the design of stabilizing landslide slope. Using piles in the base of the slope with their anchoring in soil can improve the stability of the analyzed area with an increase in the stability factor to a safe value FS = 1.6. The resulting improvement in stability of slope will be sufficient in accordance with the technical requirements. The numerical simulations of the landslide showed that such analysis could be a useful tool in the design process landslide stabilization.
