Abstract: An analytical solution for shear distribution of anchor under pull load is present by considering the progressive failure of anchor-soil interface, based on Mindlin solution of force at a point in the interior of a semi-infinite solid. Then an analytical program is developed accordingly, and the flow chart of program is also presented. The results of analytical solution and the field measurements all show that peak value of resistance at the anchor-soil interface transfers to the distal end of the bonded length as the applied load increases. Further, the effect of soil elastic modulus and anchor diameter on shear distribution between anchor and soil is studied by using this analytical model. The result shows that greater soil elastic modulus leads to greater peak shear magnitude under the same load while greater anchor diameter leads to smaller peak shear magnitude.

Key words: Geotechnical engineering, anchorage engineering, anchor shear, analytical solution
