Design optimization of anchor support system in large scale underground engineering based on finite element analysis
The anchor support design is a major content for the design of underground engineering. Proper intensity of anchor support measures helps to guarantee the surrounding rock stability and meanwhile reduce costs. A computational algorithm is proposed to optimize the anchor support design scheme using finite element analysis. The optimization is conducted by comparing calculation results of different intensities of anchor support schemes. The distribution of damage zone, the magnitudes of surrounding rock deformation and the magnitudes of anchor bolts stress are employed to quantitatively assess the reinforcing effects of supporting measures. A case study is done on a large scale hydropower plant. By implementing the proposed method, different intensities of anchor support design schemes are optimized, thus indicating the efficiency of the optimization algorithm.
