| 摘 要： | During the construction of some large-scale rock engineering, high-steep slopes and insufficient slope stability induced by unloading fissures are often encountered. For the reinforcement of these slopes, some techniques （including conventional pre-stressed anchoring cable and unconventional anchoring hole） are usually uti- lized, however, having several obvious defects. Thus, it is very difficult for a designer to design an efficient reinforcement scheme for the high-steep slopes. For this reason, the authors develop the pre-stressed anchoring beam technique, in which tensile capacity of pre-stressed structures are fully utilized. It is analyzed that the new technique is characterized by multi-functions, including engineering investigation, efficient reinforcement, drainage, monitoring and urgent strength supplement, and hoped to be extensively applicable in the reinforcement of high-steep slopes.
