Implication

Theoretical modeling demonstrates effective compliance tensor summation for seismic wave propagation in fractured rock, suggesting orthorhombic behavior for isotropic backgrounds.

Key Points

To formulate a simple method for calculating the impact of realistic fracture sets on seismic wave propagation using effective compliance and stiffness tensors.
Expressed the effective compliance tensor of fractured rock as the sum of an unfractured background rock compliance tensor and second-rank compliance tensors for each aligned fracture set.
Calculated the stiffness tensor by matrix inversion and validated theoretical models against ultrasonic experimental data from simulated fractured media.
Demonstrated that an isotropic background rock with fractures possessing equal normal and shear compliance yields effective orthorhombic elastic symmetry regardless of fracture orientation distribution.
Confirmed through ultrasonic testing on a simulated fractured medium that air-filled fractures exhibit near equality between normal and shear compliance.
