预应力锚索护壁桩在深基坑支护中的应用

针对施工场地狭小,拟建建筑物临近公路或其他建筑物的工程项目,在深基坑施工中采用预应力锚索护壁桩支护与不支护放坡开挖进行了对比分析,并对预应力锚索护壁支护法的施工工艺及质量控制作了简述,实践表明该支护方法取得了较高的社会效益和经济效益,值得推广应用。

The application of pre-stressed anchor retaining pile in deep foundation pit support

According to the engineering projects with narrow construction site,proposed buildings near highway or other buildings,this paper compared and analyzed the used pre-stressed anchor cable retaining pile support and un-support slope excavation in deep foundation pit construc-tion,and briefly introduced the construction technology and quality control of pre-stressed anchor cable retaining wall support method,the prac-tice showed that the support method achieved higher social benefit and economic benefit,worthy of popularization and application.
