摘要
在预应力锚索抗滑桩的设计计算中,锚索预应力的取值对抗滑桩的内力计算影响较大,其计算方法仍然是一个需要深入研究的课题,笔者在总结锚索预应力计算方法的基础上,介绍了锚索与桩变形的协调原理,并结合工程实例对其中的3种计算方法进行了对比研究。
The technique of anti-sliding pile with prestressed anchoring cable is a new kind of retaining structure, which nowadays has wide application in landslide control works. Prestressed force influences internal force of the anti-sliding pile in the design of anti-sliding pile with prestressed anchoring cable; however, the calculating methods of prestressed force need more attention and further research work. The paper summarizes the methods of calculating prestressed force and introduces the principle of deformation consistence between the pile and anchoring cable. Comparative study on the three methods of calculating prestressed force is made by project practice.
