管缝式锚杆(Split Set)具有安装方便、价格低廉,安装完毕后即能在全长上承受荷载,适用于各类岩石等许多优点,因此,我国的一些矿山已开始逐渐推广使用。由于矿石、围岩的性质及其破碎程度不同,对锚固力的大小要求也各有差异。对于像这样一种能适应于各种岩石条件而有发展前途的支护材料,研究如何计算在各类岩石中锚固力的大小,是很有必要的。为此,本文就管缝式锚杆在岩孔内的受力进行了分
Split Set has many advantages such as convenient installation, low price, full load after installation, suitable for all kinds of rocks, etc. Therefore, some mines in our country have started to be used gradually. Due to the nature of ores and surrounding rocks and the degree of fragmentation, the requirements for the size of the anchoring force are also different. It is necessary to study how to calculate the anchoring force in various types of rock for such support materials that have a promising future that can be adapted to various rock conditions. For this reason, this article points out the stress of pipe anchor bolt in the rock hole
