摘要

This investigation employed a comprehensive limit equilibrium method that adhered to the Mohr-Coulomb yield criterion to assess the extraction of an inclined strip anchor set in layered, cohesionless soil. The soil situated above the anchoring component counteracted the resultant extraction forces. The analysis commenced by presuming the resistant soil area enveloped within the linear failure planes extended from the edges of the anchor plate toward the ground level. Kötter’s equation was utilized to compute the corresponding soil reactions formed along the presumed failure plane. Through optimizing this assumed failure plane, the outcomes are presented in the form of a non-dimensional pullout factor. This study examined the impact of unit weight, friction angle of sand, embedment depth, dense layer thickness ratio, and anchor orientation. The analytical investigation revealed that the vertical uplift resistance intensified with an augmented anchor inclination, whereas a more pronounced decline in pullout resistance was evident for shallow embedment depths. The precision and validity of the analytical solutions were authenticated through a comprehensive comparative analysis to provide reassurance and confidence in the research findings.
