| 摘 要： | 提出用可控浆液浓度的注浆锚杆加固岩体的新工艺。该工艺可根据岩体中裂隙开度不同，沿锚杆孔深度改变水泥浆液的浓度，从而在巷道周围形成胶结密实的岩石砼拱，提高巷道的稳定性。

| Abstract: | This paper presents a new technology in which grouting-bolts with controllable grout-density are used to reinforce rockmass. According to the different degrees of rock fracturing, the technology cna adjust the density of cement-grout along the depth of bolt-holes. Consequently, a cemented compact rock-concrete arch is formed and the stability of tunnelsis improved. |
