| Abstract: | The tunnel supporting of broken rock mass has always been a major problem perplexing the mine production and construction in China.The huge amount of repair of broken tunnel supporting not only makes the whole mine production in trouble,but also causes huge economic losses every year.Therefore,the research on tunnel supporting is very important.In this paper,combined with the requirements of expanding production scale in Yangshanzhuang mining area,taking the broken rock mass as a bad engineering rock mass as the research object,The supporting method suitable for broken tunnel is put forward,and the finite difference geotechnical engineering analysis software FLAC3D is used to simulate the supporting of broken surrounding rock tunnel in Yangshanzhuang mining area,the influence of excavation on tunnel deformation on stability and finally is studied,the selection bolt grouting supporting determined. |
