Bolt and anchor cable only quantitative difference, not a qualitative difference, only the Zhang La medium. Cable tension is a steel wire production, high strength bolt is planished concrete mainly steel, usually cable applied in large tonnage anchorage engineering. Cable lacing is used by steel wire production, are made of steel or steel bolt.

Usually the cable stress is larger, but also add to the stress, stress the form of anchoring section and the free section, can be used as a permanent anchorage engineering. Anchor bolts are one, we are. In the domestic, in general, is the need for prestressed anchor, therefore it is the active force, is more and more used in already appeared on Deformation deformation or demanding engineering site; prestressed anchor is generally not ( sometimes exerted little prestressed ), so it is a passive force, only when being anchoring rock mass deformation occurs when it play anchoring force. In addition, a cable length in 2050 meters, the anchor rod is less than 20 meters.

In the world, is a type of anchor bolt. Frame foundation beam with prestressed anchor cable supporting structure with prestressed anchor cable prestress will exert on the sliding rock and soil and rock mass is closely connected as a whole, increase the level of rock and soil sliding resistance, but also through the slope of each anchor frame beam effectively as a whole, from the outside to the inside to form a reinforcing system, so as to achieve the purpose of preventing the whole slope instability, is a new type of anti slide structure.
