预应力锚索在漳诏高速公路边坡防护工程的应用

Application of Prestressed Anchor Bar in Slope Protection Work of Zhangzhou-Zhao 'an Expressway Project

在公路建设的边坡工程中,当潜在滑体沿剪切面的下滑力超过抗滑力时,就会出现沿剪切面的滑移和破坏。为了防止这种滑移和破坏,保持边坡的稳定,常采用大量削坡和设置桩墙支挡结构的方法,但在许多种情况下,以上方法往往是不经济或不可实现的,而预应力锚索以其诸多优势开始在边坡防护中得到应用。本文以漳诏高速公路预应力锚索边坡防护为实例,介绍预应力锚索的施工技术。

Side slope in highway construction will experience skipp in g and damage along the shear plane if skipping force of potential skipping unit along the shear plane exceed the anti-skipping force. The measures such as slop e cutting and retaining wall to prevent such skipping and damage and maintain the stability of side slope are uneconomic and impracticable in many circumstances . Prestressed anchor bar began to prevail in slope protection due to its numerous advantages. This article gives a introduction to ...
