Anchoring effect of pressure-type anchor rods on anchored section

The pressure-type anchor rod, a new rod type, conquers the performance deficiencies of stretched rods, such as conspicuous peak values of bond stress, poor antiseptic property, inconvenient dismantlement of rod body, and so on. Such type anchor rod is of particular mechanism and good service ability. Utilizing the function solution of Love displacement and stress of a node in the infinite body under single force, the distribution of shear stress and displacement around the anchoring section is deduced. Using the mathematic tools of Mathmatica and Matlab, the displacement isoline of the rock and soil around the anchorage is obtained. The conclusion is validated by the numerical simulation of Ansys. The characteristics of anchoring effect are given by comparing the theoretical results with the simulated ones.
