Static elastic deformation in an orthotropic half-space with rigid boundary model due to non-uniform long strike slip fault

Abstract

The solution of static elastic deformation of a homogeneous, orthotropic elastic uniform half-space with rigid boundary due to a non-uniform slip along a vertical strike-slip fault of infinite length and finite width has been studied. The results obtained here are the generalisation of the results for an isotropic medium having rigid boundary in the sense that medium of the present work is orthotropic with rigid boundary which is more realistic than isotropic and the results for an isotropic case can be derived from our results. The variations of displacement with distance from the fault due to various slip profiles have been studied to examine the effect of anisotropy on the deformation. Numerically it has been found that for parabolic slip profile, the displacement in magnitude for isotropic elastic medium is greater than that for an orthotropic elastic half-space, but, in case of linear slip, the displacements in magnitude for an orthotropic medium is greater than that for the isotropic medium.

Effect of an Infinite Surface Breaking, Inclined, Dip-Slip Fault in Viscoelastic Half Space Under Tectonic Forces on Displacement, Stress and Strain

“…H(t 1 ) is the Heaviside step function which gives the displacement at any point Q(y 2 , y 3 ) and φ(y 2 , y 3 ), φ 1 (y 2 , y 3 ), φ 2 (y 2 , y 3 ) are given in Appendix. We try to find the solutions in the following form: We consider different dislocation function f (ζ ′ 3 ) in the following form suggested by Godara et al [11]:…”

“…2016; Godara et al 2017). For rocks with strong heterogeneity, along the extension direction of the strata, with the change of rock properties, the differential stretching or shearing of strata will have a significant effect on the distribution of faults (Morley 2013; Misra and Gupta 2014;Ozcelik 2016).…”
