分析了预应力锚杆支护的机理,探究了影响支护效果的主要参数。在巷道支护工程中应该根据实际情况确定各项参数,并以具体实例探讨预应力锚杆支护效果,结果显示,预应力锚杆支护技术能够良好地控制巷道变形,稳定性和安全性更高。
The mechanism of prestressed bolt support is analyzed and the main parameters affecting the supporting effect are explored. In the roadway support project, the parameters should be determined according to the actual situation and the supporting effect of prestressed anchor is discussed with concrete examples. The results show that the prestressed bolt supporting technology can well control the deformation, stability and safety of the roadway higher.
