中文摘要：

尽管锚索桩在我国的边、滑坡治理工程中应用得非常多,但其设计计算理论却并不完善,远滞后于工程实践。现有的锚索桩计算模型只是在普通抗滑桩计算模型的基础上作简单修改后得到的,仅仅增加了锚索对桩的约束条件,这样虽能反映锚索桩是一种受约束的桩,却不能反映锚索桩主动式受力的特点。该文通过对桩锚协调变形机理的分析,探讨了一个合理、真实、完整的预应力锚索桩计算模型的三个重要环节,并建立了更加合理的桩锚协调变形方程。

英文摘要：

Although anchor anti-sliding pile is widely used in side slope and landslide treatment engineering in our country, design and calculation theory is not perfected and lag behind engineering practice. The existing calculation model of anchor anti-sliding pile is formed after simple improvement on the calculation model of common anti-sliding pile, just with more constraints of anchor on pile. This can present the anchor pile is a constrained pile, but cannot reflect the active force characteristics of anchor pile. Based on the analysis on pile-anchor coordinated deformation mechanism, three important stages of the calculation model of reasonable, real and complete prestressed anchor pile are discussed and a more reasonable equation of pile-anchor co- ordinated deformation is establishes.
