The article presents a method for earning soil shear modules from the results of micropile loading tests. The micropile is first loaded with a push force and then with a pull force. The shear modules are derived from two graphs of the dependence of micropile displacements on the loading forces. One represents a push and the other a pull test. Three values of soil shear moduli are obtained, namely for elastic deformation, plastic hardening and the last one after soil failure at a slip plane on micropile shaft.
