端部锚固与全长锚固作用效果分析
Analysis on the working result of point-and-fully-anchoring of bolts
【摘要】 针对端部锚固和全长锚固两种不同的锚杆锚固形式 ,利用莫尔圆和抗剪强度包络线从岩体的剪切参数及岩体所受支护反力方面对锚固的挤压加固效果进行了分析比较 ,提出了锚杆锚固的强度储备概念 ,并得出了端部锚固和全长锚固强度储备的计算公式以及二者强度储备比值的计算公式
【Abstract】 In terms of point_and_fully_anchoring of bolts, the compression and consolidation effect of anchoring is compared and analyzed by means of Mohr′s circle and shear strengh envelope curve from the shearing parameters of rock mass and the interacting force offered. A new concept about strength reserve is also put forward. In addition, the formula of strength reserve of point_and_fully_anchoring, together with that of the ratio of strength reserve of fully_anchoring to point_anchoring is obtained.
