摘　　要：对于规模较大的滑坡处治,若地层难以提供足够的锚固力,且地下水丰富,传统抗滑桩施工风险较大。桩顶通过系梁连接的机械成孔的门架式抗滑桩彰显其独到优势。对此,基于弹性地基刚架理论,建立刚架抗滑桩的设计计算方法,并通过工程实例进行验证。结果表明:治理效果较好,保障了沈海高速复线罗溪互通的运营安全。It is in highly-risk to simply choose regular anti-slide piles to control large-scale and water-rich landslide, especially when the soil is unable to support enough bearing force. As proved, the portal rigid-frame anti-slide piles are obviously more reasonable and efficient on the prevention and treatment of landslides mentioned above. The portal rigid-frame anti-slide piles are quickly and safely constructed by machinery, and the front and back rows of piles are connected by beam on the top. In this paper, the design and calculation method is established based on elastic foundation theory and proved to be reliable in many engineering projects. Consequently, the method is quite instructive on similar kinds of landslide treatment.
