摘要
在分析了国内外可伸长锚杆类型的基础上，介绍了中国矿业大学研制的力学性能好、加工简单、价格较低、实用性强的Ｈ型及改进型杆体可伸长锚杆的原理和结构。不同现场地质条件下的３个工程实例证实了使用Ｈ型及改进型杆体可伸长锚杆的必要性及所取得的显著技术经济效益。
Based on the analysis of the rockbolts with extensible rod used in the world, the principle and structure are introduced of the type H and modified type of rockbolts with extensible rod developed by the China University of Mining & Technology, which are good in mechanical performance, simple in manufacturing, low in cost and excellent in practice. The positive results of three examples in site under different geological conditions have proved the necessity of using the rockbolts with extensible rod and remarkable techno-economic benefits made.
