摘要
根据预应力锚索在边坡加固中的主动加固机理 ,分别讨论了仅考虑锚固段、自由段及同时考虑该两段时锚索的最优方位角和最优锚固长度的确定方法。结合工程实例 ,介绍了它们的确定过程。经现场反馈的信息及分析表明 ,该设计方法较为合理 ,可供设计单位参考。
According to the active solidifying mechanism of cable anchor,the method of selecting the optimum directional angle and rational solidifying length of cable anchor are discussed for the case of considering only the solidifying section or free section and the case of considering both sections simultaniously.Informations from mines where the method has been adopted and the systematic analysis of the method show the method is reasonable and practicable.
