| 摘 要： | 采用一种体积较小的电阻应变砖,对软岩中压力型锚索在工作荷载作用下锚固段砂浆体内部三向应变进行了测试,通过对试验测试数据的分析,得出了压力型岩锚锚固体应变分布规律。采用软岩条件下的参数,推算出各测点锚固体应力大小,通过对锚固体的受力分析并与理论值进行对比,总结出软岩条件下锚固体应力分布特点,为压力型锚索的进一步理论研究和工程应用提供参考。

| Abstract: | Used a small volume resistance strain brick, tested the strain on the anchorage segment mortar of pressure-type anchor which in soft rock, under the action of working load. Obtained the strain distributions of pressure-type rock anchor through analysis of the experimental test data. Parameters in soft rock conditions, calculate each measuring point stress and distribution of anchorage body. In the end, compared with the theoretical value of anchorage body, summed up the anchorage body stress distribution of pressure-type rock anchor under the soft rock conditions, it will provide reference for further theoretical research and engineering applications of pressure-type rock anchor. |
