Meanwhile stationary pressure and liquidsurface test result is used combining with the production data, the effective analysis and prodiction to reservoir development andfracture layout as well as exploitation rules have been made.

Analysis for fracture propagation and stimulation under multi-pulse gas load fracturing;

Controlling action of sandout belt at fracture periphery on fracture propagation.;

Mechanism of hydraulic fracture propagation in fracture-cavity carbonate reservoirs

Analytic model for tracing crack propagation under coupled mechanical-hydrological environment;

Analytic model for crack propagation under coupled mechanical hydrological environment;

Measuring crack propagation in reinforced asphalt concretes;

Compared with the classical finite element method,the crack growth in the gravity dam can be modeled by XFEM without making the .

Experimental results show that the maximum speed and accelaration ofcrack growth increases with the loading rater, the dynamic fracture toughness increases with the crack growth speed, the per-peak crack growth increases with theloading rates.

The influence of steel bar on crack extension of concrete faced rock-fill dam;

And by comparison of uniaxial tension model and crack extension model, the relationship between the increase of inelastic strain and crack extension was discussed.

This model has been applied to simulate the crack extension in three point bending creep test.
