浅谈预应力锚索高边坡动态加固设计在客专工程中的应用

Elementary Discussion on Application of Pre-stressed Anchor Cable High Slope Dynamic Reinforcing Design in Passenger Train Engineering

该文结合工程实际,介绍了预应力锚索技术在石武客专SWZQ-9标DK1040+875～915右侧桩顶一级边坡路堑边坡防护中的应用情况。通过实践表明,对一些风化严重的高陡边坡采用预应力锚索进行加固,提高岩土的稳固力和层间正压力及摩阻力,阻止散岩体位移,从而达到加固边坡的目的,增强边坡的整体稳定性,具有较好的防护效果。此种防护形式在类似的边坡整治工程中可推广应用。

Combined with the engineering cases,the article introduces the application of the pre-stressed anchor cable technique in the cut slope protection of the Class I slope at the top of the right side pile DK1040+875-915 in Shiwu Passenger Train SWZQ-9 Bid.The pre-stressed anchor cable is used to reinforce some seriously weathered high-steep slopes to enhance the steadying capacity of the rock and the positive pressure and frictional resistance and to prevent the scattered rocks from displacement so as to achieve the objective of reinforcing the slope and to strengthen the integral stability of the slope with thebetter the protective result.This protective mode can be spread and applied in the similar slope reinforcing projects.
