Research on Construction Technology of Prestressed Anchor Cable in Expressway Slope Support

为提高边坡支护中预应力锚索的施工质量,使边坡支护效果达到最佳,开展预应力锚索施工技术的深入研究。基于MATLAB软件模拟高速公路边坡情况,以保证每级边坡支护效果为前提,完成预应力锚固参数设计。以设计参数为基础,结合边坡支护工程锚孔布置图布设锚孔,制作并放置预应力锚索,进入锚索灌浆工序,完成施工。应用分析可知,应用论文所提施工技术,边坡土体沉降量较小,边坡支护的稳固性较高,支护效果优势显著。

In order to improve the construction quality of prestressed anchor cables in slope support and achieve the best slope support effect,this paper conducted in-depth research on the construction technology of prestressed anchor cables.Based on MATLAB software to simulate the slope situation of the highway,in order to ensure the effectiveness of each level of slope support,the design of prestressed anchoring parameters is completed.Secondly,based on the design parameters and combined with the anchor hole layout of slope support engineering,anchor holes are arranged,prestressed anchor cables are made and placed,and the anchor cable grouting process is entered to complete the construction.Application analysis shows that the application of the proposed construction technology results in a smaller settlement of the slope soil,a higher stability of the slope support,and a significant advantage in the support effect.
