The Parallel Slice Method for Analysis of Soil Nailing Based on Genetic Algorithm
Publication: Advances in Earth Structures: Research to Practice
Abstract
A new design methodology was developed to analyze the stability of soil nailing and forces in soil nails. In soil nailing, nails were generally designed to be parallel to each other. A new way to separate soil and nails into slices was developed in this study, in which the failure wedge of soil and nails were divided into a number of slices parallel to nails. By the proposed method, both the safety factor of soil nailing and the forces in soil nails could be obtained respectively. The critical slip surface and the limit state of soil nailing were determined by the proposed method combining with modified genetic algorithm (GA) which was based on simple GA and merged with traditional optimal methods such as complex method and had the advantages as global convergence and fast convergence rate. This proposed method was validated by comparing the predictions with practical observations.
