补充资料：岩体锚固
| 岩体锚固 rock mass，anchorage of 利用锚杆或锚索稳定裂隙岩体的措施。它的主要作用是引起岩体的附加应力和应变，借以增大岩体的整体性，抗拉强度及软弱面的剪切强度以及抗滑切向力，从而使岩体稳定。锚杆通常为钢制杆件 ，直径一般为1.6～2.8厘米，长度根据需要而定，多在1～6米之间。以锚杆头部的锚固装置和尾部的紧固装置固定岩体的叫集中锚固。将锚杆和孔壁之间全部空隙用砂浆或树脂填充胶结，加固岩体的叫全长锚固。此外，按锚头特点，锚杆分为楔缝式、涨壳式、爆固式和树脂式等；按受力特点，锚杆分为有预应力和无预应力两类。锚索为高强钢丝束、钢绞线、钢丝绳或粗钢筋等。长度根据需要确定，一般在10～40米。分内锚固、外锚固和张拉段。用锚索加固岩体场施加预应力。用来加固岩体的锚杆，锚索等锚固部件均设在岩体内部。 |
