预应力锚索抗滑桩实用设计方法及工程应用

Practical Design and Application of Stabilizing Piles With Pre-stressed Anchored Cables

本文结合长城矿边坡加固工程,通过比较不同设计方法总结了关键计算参数,如:抗滑桩桩后推力,抗滑桩位置,桩间距,桩身锚固长度,锚索预应力值等的优化选取,编制了抗滑桩工程从方案优化至单个构件的完整计算步骤和设计框架流程,为同类预应力锚索抗滑桩工程设计提供了可靠的实用设计方法。

This paper summarizes the selection of key calculate parameters for example： anti - slide pile thrust, anti - slide pile position, pile spacing, pile anchor length, anchor cable pre - stressed value and so on are optimized after comparing the different calculation method, and stabilizing pile design frame process are described from scheme optimization till component design combine with the applications of slide slop protection engineering in Great Wall Coal Mine. The practical design method of the similar stabilizing pile with pre - stressed anchor cable engineering is available.
