Abstract

On the supposition that the shear resistance increases linearly with shear displacement between the bolt and surrounding soil,a calculation model of load transfer with hyperbolic function is established.The distribution of frictional resistance and shear displacement along the anchoring length and the influence factors are obtained.Based on the field uplift tests of 4 grouted bolts buried in clay,the load transfer behaviors of bolt are described.The calculated values are compared with the results of tests,and good agreements are obtained
