摘要
分析了锚喷支护在软岩巷道应用中的失效原因,在此基础上,对纤维混凝土柔性喷层的应用进行了细致的研究。研究结果表明,柔性喷层能够增加喷层极限变形量,提高喷层残余强度,有效防止锚喷支护失效。
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.
