公路高边坡预应力锚索抗滑桩施工技术

Construction Technology of Prestressed Anchor Cable Anti-Slide Pile on Highway High Slope

本文以某高速公路工程为例,根据高边坡施工条件,研究预应力锚索抗滑桩施工技术,涉及抗滑桩、预应力锚索的关键施工工序及具体方法,并根据监测结果分析高边坡支护效果,评价预应力锚索抗滑桩施工技术的可行性,同时提出锚索抗滑桩的施工质量控制要点。实践表明,在联合应用抗滑桩和预应力锚索后,高边坡的位移量被控制在允许范围内,预应力锚索抗滑桩施工技术具有可行性。

Taking a highway project as an example,according to the construction conditions of high slope,this paper studies the construction technology of prestressed anchor cable anti-slide pile,involving the key construction procedures and specific methods of anti-slide pile and prestressed anchor cable,analyzes the supporting effect of high slope according to the monitoring results,evaluates the feasibility of the construction technology of prestressed anchor cable anti-slide pile,and puts forward the key points of construction quality control of anchor cable anti-slide pile.The practice shows that the displacement of high slope is controlled within the permissible range after the combined application of anti-slide pile and prestressed anchor cable,and the construction technology of anti-slide pile with prestressed anchor cable is feasible.
