| Abstract: | In view of the difficult control of the deformation of large section chamber surrounding rock under complex conditions，the field investigation，theoretical analysis and numerical simulation were used to study the deformation of surrounding rock.The calculation formula of the deformation of surrounding rock was derived，the factors affecting the deformation of the surrounding rock of the chamber were analyzed，and the orthogonal test method was used and the optimum support parameters were obtained by combining the numerical simulation software FLAC，and the large section control technology of chamber surrounding rock was put forward.Field practice showed that the deformation of chamber surrounding rock was within the control range，and chamber support was stable. |
