压力分散型锚索在高边坡支护中的应用

The Application of Pressure-dispersed Anchor Cable to High Slope Support

预应力锚索在高边坡支护治理工程中得到广泛应用,压力分散型锚索能提供更大的锚固力,是治理破碎高边坡的重要手段。近年来在公路市政边坡、水利水电和建筑边坡的支护设计中较多采用,压力分散性锚索在高边坡支护实际应用上取得了较好的效果。根据预应力锚索在高边坡治理工程中的应用实例,针对其施工技术规范要求、技术特点、施工工艺、施工中的关键环节及经济效益结合工程实例进行了论述,为高边坡支护设计和施工提供了宝贵经验。

The prestressed anchor cable has been widely applied in high slope treatment engineering, yet the pressure-dispersed anchor cable is more important means of broken high slope treatment for its greater anchorage force. In recent years, the pressure-dispersed anchor cable is widely used in municipal highway slope, water conservancy and hydropower construction and slope supporting design, and has achieved better effect in practical application. According to the application examples of prestressed anchor in high slope treatment engineering, the paper discussed its requirement of construc- tion technology, technical features, construction technology, key links in the construction and economic benefits, and provided valuable experience for design and construction of high side slope support.
