MODIFIED APSO BASED SLOPE STABILITY ANALYSIS USING NON-CIRCULAR SLIP SURFACE
In evaluating the stability of natural slopes that have multiple layers with different soil strength, the safety factors obtained by slope stability analysis using a circular slip surface are not guaranteed to be the smallest safety factors, but the safety factor with non-circular slip surface can o...

| description | In evaluating the stability of natural slopes that have multiple layers with different soil strength, the safety factors obtained by slope stability analysis using a circular slip surface are not guaranteed to be the smallest safety factors, but the safety factor with non-circular slip surface can obtain reasonable slip surfaces with a smaller safety factor. This paper describes safety factor calculation of four slope models with simple or complex strata with a non-circular slip surface using the widely adopted particle swarm optimization method and a newly developed adaptive particle swarm optimization method. The proposed adaptive particle swarm optimization method is shown to be superior in terms of computational accuracy and speed. |
