The paper presents the pullout capacity of inclined strip anchors embedded in cohesionless soils using finite element-based lower bound limit analysis and nonlinear optimization. The pullout capacity of inclined anchors with various angles of inclination, embedment depth, and soil properties have been presented. It is observed that pullout capacity of inclined anchors nearly remains constant up to an inclination angle of 30° and thereafter increases significantly with an increase in the inclination angle. It is also observed that as expected the pullout capacity of inclined anchors increases as the embedment depth and internal friction angle of cohesionless soil increase.

摘要

The paper presents the pullout capacity of inclined strip anchors embedded in cohesionless soils using finite element-based lower bound limit analysis and nonlinear optimization. The pullout capacity of inclined anchors with various angles of inclination, embedment depth, and soil properties have been presented. It is observed that pullout capacity of inclined anchors nearly remains constant up to an inclination angle of 30° and thereafter increases significantly with an increase in the inclination angle. It is also observed that as expected the pullout capacity of inclined anchors increases as the embedment depth and internal friction angle of cohesionless soil increase.
