Abstract:Using FLAC-3D,the excavation and the effect of support are analysed for Fenggang segment of Dong-Shen water supply tunnel. It is considered how to select rock mechanics parameters after the surrounding rock masses are loosing under the influence of blast,and some useful conclusions are gained.
