摘　　要：在分析国内外已有抗滑结构研究现状基础上,针对目前滑坡治理主要抗滑桩结构——普通抗滑桩和预应力锚索抗滑桩等结构型式,分析了抗滑桩室内外试验、内力计算方法、桩间距的确定方法、桩位布置及锚固深度的确定方法研究现状,重点探讨了围桩-土耦合式抗滑桩和新型拱弦式耦合抗滑结构的研究现状及未来发展趋势。进一步提出滑坡防治效果后评价的思路与方法,强调在桩-土耦合发挥土自身强度的前提下,开展滑坡防治新理论和新技术的推广应用;结合高速铁路路基蠕滑治理要求提出了“零位移”控制的新型抗滑结构,为新型抗滑桩结构研究提出了新的思路和研究方向。Based on the analysis of existing anti-sliding structure and the research status at home and abroad, according to the current main landslide anti-slide piles and prestressed anchor cable anti-slide pile structure of ordinary structure, this paper analyzes the anti-slide pile indoor and outdoor test, internal force calculation method, calculation method of pile spacing, pile method for determining the position and the anchoring depth research present situation. It discusses the circumference coupling anti-slide pile - soil and the structure of the new type arch string coupling anti-sliding research present situation and development trend in the future. Furthermore, the idea and method of post-evaluation of landslide prevention and control effect are put forward, and the popularization and application of new theory and technology of landslide prevention and control are emphasized on the premise that the pile-soil coupling gives full play to the soil's own strength. A new type of anti-sliding structure with "zero displacement" control is put forward according to the requirements of controlling creep slip of high-speed railway roadbed.
