APPLICATION OF THE ANSYS SOFTWARE TO SOLVING COUPLING OF IN-SITU STRESS AND FLUID

The coupling of the in-situ stress and fluid is the research focus in recent years and also an important subject in research on rock and soil engineering and geology.So it has prominent significance to find out a simple method to solve the stress-fluid coupling equation.In this paper, a simple method of solving the stress-fluid coupling equation at certain boundary conditions is proposed based on the corresponding relation of the seepage equation of stress-fluid coupling and heat conduction equation and using the structural mechanical module and heat conduction module in the ANSYS software.The results obtained from the method are in good agreement with the theoretical solution and actual outcomes.
