补充资料：喷锚支护
| 喷锚支护 combination of anchorage and shotcrete support 把锚固和喷混凝土结合起来，用以加固地下洞室围岩的措施。喷混凝土是利用喷浆设备向地下洞室开挖面喷一定厚度的混凝土层，借以支护围岩。由于混凝土喷层密贴围岩，并具柔软性等特点，所以能承受较大荷载，并能控制围岩变形，充填胶结岩体表层裂隙，保护和发挥岩体的潜力。喷混凝土可以作为洞室围岩的初期支护，也可以作为永久性支护。喷锚支护是使锚杆、混凝土喷层和围岩形成共同作用的体系，防止岩体松动、分离。把一定厚度的围岩转变成自承拱，有效地稳定围岩。当岩体比较破碎时，还可以利用丝网拉挡锚杆之间的小岩块，增强混凝土喷层，辅助喷锚支护。 |
