Abstract: On the assumption that any part of displacement of anti-float anchor is linear elastic relation, the relations about frictional resistance, axial force and displacement between soil and bolt can be derived by applying the mechanics theory. The example shows that based on the linear elastic analysis model, the formulas of frictional resistance, axial force and displacement can describe the elastic stress and strain better. The distribution of frictional resistance and shear displacement along the anti- float anchoring length are obtained. It comfirms that the shear displacement between the bolt and surrounding soil is main displacement for the bolts buried in soil.

Key words: anti-float anchor, linear elasticity, frictional resistance, axial force, shear modulus
