Abstract
After 5・ 12 earthquake in Wenchuan, the slope stability has been severely damaged in earthquake area, many destroyed modes appeared, such as collapse, landslide, deformation, and so on.Pre-stressed anchor cable is the main method of preventing high slope harm, with large tonnage pre-stressed cable anchoring in stable rocks of slope to resist the deep slope failure and deformation by pre-stressing.It is important to monitor the pre-stress variation, through the pre-stressed state monitoring both in and after construction process, the reinforcement effects can be tested and based on the long-term monitoring results to evaluate the slope stability state, whether to take appropriate remedial measures can be de-cided.According to the slope anchor cable reinforcement of Futang hydropower station after earthquake and the stress moni-toring, the paper discusses the stress loss of pressure-dispersive anchor and the variation rule.关键词
