Undrained Response of Fluid-Saturated Fissured Rock
A classical Biot theory of the time-dependent response of fluid-saturated media was formulated for the porous material, with the microstructure formed by small pores interconnected by narrow channels. The stress-strain relations for such media are isotropic. In addition to pores, rock materials often contain a network of narrow, crack-like fissures. Since the deformational response of a fissure to the external load depends on its orientation with respect to the load, the undrained ('instantaneous') fluid pressures will be different in fissures of different orientations ('pressure polarization'). Therefore, stress interactions between cracks will be coupled with fluid pressures in crack cavities. These coupling phenomena are considered on the basis of the recently developed method of analysis of many cracks problems. This method is modified to account for the presence of compressible fluid in cracks. (ERA citation 12:033990)
