Abstract EN
A numerical simulation approach of hydraulic fracture process, considering the couplings of the stress distribution, the fluid flow of the water-air mixture, the compression and dissolution of air, and the element damage evolution, has been developed to investigate the mechanisms of crack initiation and propagation in porous media during hydraulic fracturing.
The concept of homogenized pore fluid has been adopted to represent the water air mixture.
A large number of numerical analysis on hydraulic fracturing in clay with incipient injection slot have been carried out to study the mechanism of hydraulic fracturing in unsaturated soil with the characteristic of critical model I type of crack loading using stress intensity factor K Ic .
The results provide a numerical picture depicting the mechanisms of crack initiation and propagation during hydraulic fracturing.
The numerical results are in good agreement with the experimental results, which confirms the adequacy and the power of the numerical approach.
