Double porosity poroelasticity and its finite element solution,concern due to potential rock movements along fractures at the borehole wall. In the case of shale formations, not only does the state of stress and pressure play a role, but also the properties and interactions between the shale and the drilling fluid.

Stress-dependent permeability, the influences of the pore pressure and stress changes. Various attempts have found that stress-deformation behavior of fractures and pores present in rock masses is a key factor governing rock permeability and fluid flow through the rock masses.

When the rock samples are not available, such as oil and gas drilling and mining at deep depth, the well log data and geophysical data can be used to analyze and interpret rock physical and mechanical parameters (Peng 1997, Peng 1999).

The so-called garage refers to ancillary buildings belonging to the whole community, with independent space for the purpose of storing vehicles. Garages are not limited to underground garages; some are on the first or second floor above the ground.
