摘要
针对巷道支护技术的现状,研究了在动压软岩巷道中使用锚杆支护技术的特点以及存在的问题,提出了一种新型的适用于动压软岩巷道中的让压锚杆,介绍了该新型锚杆的设计原理及总体结构,然后对锚固头的受力特点进行了研究和分析,通过理论推导和仿真求解得到其性能曲线。分析表明该新型让压锚杆可以有效提高动压软岩巷道的支护效果。
According to the current situation of the tunnel supporting technology. Analyzed the features and problems in yielding bolt technology in press soft rock tunnel. Then proposed a new yielding bolt design which is suitable in press soft rock tunnel. This paper put forward the principle and design of the new bolt, and also did research and analyze on the characteristics of the bolt anchor. We get the performance profile by theoretical derivation and simulation. The result of analyze showed that this new yielding bolt can increase the effect of supporting.
