摘要
传统锚索设计方法只考虑单根锚索的悬吊作用,而忽略了群锚效应,加大了锚索加固的盲目性。稳定性图解法通过岩体工程地质调查来掌握岩体的基本特性,首先对采场进行稳定性分析,在此基础上确定其支护参数,并针对具体锚索型号验算锚固力。采场帮壁锚索加固试验证明,稳定性图解设计法是切合实际的,确定的锚索参数及受力分析是比较合理的。
The traditional design method of cable - anchor support only considers the suspension action of single one, and loses sight of the anchoring effect of cable - anchors group, increasing the blindness of cable - anchors support ground. In the stability graphical method, the basic property of rock mass is understood by engineering geology survey, the stability is analyzed at first, then the supporting parameters are determined, and the anchoring force is checked according to the type of cable - anchor. The experiment of reinforcing wall of stope with cable - anchors has proven that stability graphical method is practicable, in which the determined cable - anchor supporting parameters and stress analysis are rational fairly.
