摘要

Considering the effect on surrounding rock exerted by TBM construction and its corresponding support measures are quite different from those of drilling and blasting construction, this study attempts to investigate the disturbance of TBM construction and its countermeasures. The investigation specifies the size of the drop pieces, position and cause and provides support measures for different stability condition of surrounding rock.
