The Biot linearized theory for fluid saturated porous materials is used to study the plane strain deformation of an isotropic, homogeneous, poroelastic half space in welded contact with an isotropic, homogeneous, perfectly elastic half space caused by an inclined line-load in elastic half space. The integral expressions for the displacements and stresses in the two half spaces in welded contact are obtained from the corresponding expressions for an unbounded elastic and poroelastic medium by applying boundary conditions at the interface. The integrals for inclined line-load are solved analytically for the limiting case i.e. undrained conditions in high frequency limit. The undrained displacements, stresses and pore pressure for poroelastic half space are shown graphically.
