Stability Analysis of Layered Soil Slope Using Truncated Pile with Numerical Solution
Tóm tắt
Available literature reveals that the use of truncated pile would be a good solution to increase the stability of slope which is introduced to date for homogeneous soil. Here an attempt is made to perform both experimental and numerical studies introducing truncated piles in layered soil. Both top and bottom layers are cohesive-friction soil. The sand layer is sandwiched between these layers. The influential factors include water content variation, frequency of base shaking, types of reinforcement used, and depth of the truncation. Slopes are manually prepared and tested using a shake table instrument. The horizontal deformation, root means square acceleration, and crest deformation are evaluated and shown at different water content, frequency, and types of reinforcement. In practical engineering, the piles could be truncated reasonably while ensuring the reinforcement effect. The truncated part of piles is filled with the cement sand mortar. A 2D finite element analysis has been done to validate the results obtained from the experimental investigations. The results show that the introduction of truncated piles increases the stability of the slope. Also, the more increase in the truncated part of the pile, the more will be the effectiveness of the pile.
