GENERAL ANALYTICAL SOLUTION OF THREE TYPES OF ANCHORS UNDER TENSILE LOAD

In order to obtain a general analytical solution of threetypes of anchors, an analytical solution of inner-bonded anchor undertensile load is obtained by assuming displacement consistency between anchor and soil,based on Mindlin solution of force at a point in the interior of asemi-infinite solid. Then the analytical solution is extended to thefull-bonded anchor and compression anchor. Further, a general analyticalsolution of the three types of anchors under tensile load is obtained. Theeffect of anchor type, soil elastic modulus and anchor diameters on sheardistribution between anchor and soil is evaluated by using the generalanalytical solution. The results show that (1) there is only one stress peakalong the shear distribution curve of the three types of anchors; (2)as the elastic modulus of soil increases, the magnitude of shear increases whilethe distribution length of shear decreases; (3) as the anchor diameter increases,the magnitude of shear decreases while the distribution length of shearis almost not changed.
