山区边坡预应力锚索施工控制要点研究

Research on Key Points of Construction Control of Prestressed Anchor Cable in Mountain Slope

随着公路投资的不断加大,山区公路改扩建工程越来越多。但是,山区地势险要,地质破碎,地质构造复杂。随着公路等级的不断提高,路线所经地方设计成深路堑,越来越成为常态。为防止边坡滑塌,确保开挖的边坡稳定,人们需要对边坡进行支挡防护。目前,比较成熟且常用的是预应力锚索框架支护。本文以K5+880~K6+080右侧边坡地质情况为例,简单地分析山区预应力锚索施工控制要点。

With the continuous increase of highway investment,more and more mountainous highway reconstruction and expansion projects.However,the mountainous terrain is dangerous,the geology is fragmented,and the geological structure is complicated.With the continuous improvement of highway grades,it has become more and more normal to design deep trenches where the route passes.In order to prevent the slope from collapsing and ensure the stability of the excavated slope,people need to support and protect the slope.At present,the more mature and commonly used is the prestressed anchor cable frame support.This paper took the geological conditions of the right side slope of K5+880~K6+080 as an example to briefly analyze the key points of construction control of prestressed anchor cables in mountainous areas.
