EFFECT ON DISPLACEMENT COMPONENTS DUE TO FREE BOUNDARY AND RIGID BOUNDARY IN CASE OF DEFORMATION OF A UNIFORM HALF-SPACE CAUSED BY A VERTICAL TENSILE FAULT

Mahabir Singh, Ravinder Kumar Sahrawat, Minakshi and Meenal Malik

Closed form analytical expressions for the stresses and displacements are derived caused by a long vertical tensile fault buried in a homogeneous, isotropic, perfectly elastic half-space with rigid boundary. The Airy stress function approach has been used to calculate stresses and displacements at an arbitrary point of the half-space. The variation of the displacement field with the horizontal distance from the fault and with the depth is studied numerically and the results obtained in the case of rigid boundary are compared with that of free boundary.
