【 摘 要 】

Freeze-thaw cycles have great harm to slope anchorage structure, and the theoretical system has not been formed because there are too many constraints and interrelations. This paper analyzes the failure principle and appearance of the slope under the freeze-thaw cycles and puts forward the prevention and control measures. On the whole, at this stage there is no way to raise the anchoring technology as a system to do the whole study. It is urgent to establish a complete concept and overall evaluation mechanism of rock and soil anchoring system, because it can give full play to the function of the favorable elements in the anchoring system and weaken the harm of the unfavorable elements so that the system can achieve the best working condition.
