Theoretical Study of Behavior of Ground Anchor in Frictional Soil by the Use of the Kinematic Approach of Limit Analysis

This paper presents the results of theoretical study based on the kinematic approach of the limit
analysis for elaboration of the mechanism of failure of cohesionless soil (sand) around a single;
inclined ground anchor at the time of tension and for estimation the limit load in the case of criterion of
Mohr-Coulomb and the associated flow rule, taking into account of the mobilization of the ground in
abutment in reaction to the loading. The effect of the inclination and the length of ground anchor, the
friction angle of the soil () and the dry density were examined on the collapse load. Through this
study, it has been found that the results obtained by theoretical approach were upper than those
obtained by empirical approach (the recommendations T.A. 95).
