预应力锚索抗滑桩在滑坡治理中的应用

Application of "Pre-stressed Anchor Cable + Anti-slide Pile" Method in Treatment of Landslides

介绍了预应力锚索抗滑桩技术,对其抗滑机理、受力特点、设计原则、设计流程及相关问题进行分析,并与抗滑桩进行技术经济比较,通过在黄泥包滑坡整治中的应用,证明其较普通抗滑桩具有受力机理明确、结构合理、工程造价低、便于施工等优点,是一种具有广泛发展前途的新一代抗滑结构。

The paper presents the ＂pre-stressed anchor cable ＋ anti-slide pile＂ technology, analyzes the anti-sliding mechanisms, force bearing characterlstics, design principles, design procedures and other relevant issues of the technology and makes technical and economic comparisons between ＂pre-stressed anchor cable ＋ anti-slide pile＂ and normal anti-slide piles. The mentioned technology is applied in the treatment of Huangnibao landslide, which demonstrates that the ＂pre-stressed anchor cable ＋ anti-slide pile＂ is a new generation of anti-slide structure with broad development future, which is featured by definite force bearing mechanisms ; reasonable structure, low cost and convenient for construction.
