| 摘 要： | 全螺纹等强度锚杆是一种新型锚杆，其最主要优点是杆体不需二次加工紧固螺纹，不仅简化了生产工艺，还实现了杆体全长等强，克服了常规锚杆受拉时产生应力集中区而使杆体强度降低的缺点，另外，较大的螺距可使锚杆安装速度提高。介绍了这种锚杆的结构、性能和特点，并对其应用及支护效果作出评价，认为全螺纹等强锚杆是一种有发展前途的锚杆，是较理想的锚杆支护更新换代产品。 |
| 关 键 词： | 全螺纹等强锚杆 等强度 拉拔力 锚固力 锚杆支护 巷道支护 生产工艺 螺距 |

| Abstract: | Bolt with full screw threads and equal strength is a new type of bolt. Its mainly advantage is that the fixture screw threads are not processed at second time. So, this kind of bolt not only simplifies production procedure, but also makes the bolt body equal strength. Moreover, the installation speed of bolt can be raised by bigger crew instance. The structure, capability and feature are introduced in this paper, and its application and support effect are evaluated. The conclusion is that bolt with full screw threads and equal strength is an prospective bolt, and also an ideal upgrading product. |
| Keywords: | full screw threads equal strength drawing force bolt tightened force. |
