Back Analysis for Rock Mechanical Parameters and Calculation of Ground Stress Based on GA-FLAC3D
In order to obtain the stress distribution in deep level of Datai mine, a nonlinear back analysis method for rock mechanical parameters was proposed by combining genetic algorithm and FLAC3D (GA-FLAC3D). First the hollow inclusion stress gauge (stress relieving method) was used to complete the measurement of local in-situ stress;and then the rock mechanical parameters were obtained by using back analysis;at last the ground stress in deep level was obtained. The results showed, this method is quick in calculation, and has global convergence. The convergence accuracy of normal stress is about 90％.
