摘　　要：对不同的锚杆类型在不同条件下进行锚固力拉拨试验,得出了不同类型锚杆的锚固特性,特别是对影响砂浆锚杆锚固力的各种因素,如水灰比、灰砂比、龄期、杆体强度进行了试验研究,为巷道及采场进行锚杆支护提供了试验参数。A series of pulling tests on the anchoring force of different types of anchors were carried out under different conditions, and the anchoring characters of diverse anchors were studied. The factors affecting the anchoring characters of mortar anchor, such as water to cement ratio, cement to sand ratio, curing age, and bodily form of anchor, were studied. The experimental study has provided test parameters for anchor rod support of tunnel and stope.
