Study on Application of Fiber Concrete in Soft Rock Stratum Support |
| |
| Abstract: | The invalidation reasons of application of bolting & shotcreting support in soft rock stratum were analyzed in this paper, and based on this, the detail study on application of fiber concrete flexible shotcreting layer was given. The research result indicates that the flexible shotcreting layer can increase the limit distortion and improve residuary strength of shotcreting layer and prevent support failure of bolting & shotcreting. |
