| Abstract: | In this paper,authors obtain formulas of the stresses and displacementsaround a granular cavity in an infinite medium with different moduli in tensionand compression.From the result,the influences of the tensional parameters onthe stresses,displacements and the developments of the yielding zone aroundthe cavity are investigated and some useful conclusions are made. |
