摘要
论文针对打入式夯扩灌注桩在饱和黄土层中应用时的各种质量问题进行了原因分析,提出了打入式夯扩桩在饱和黄土中应用时的施工辅助措施,可有效降低桩身和桩顶处的水平荷载作用对成桩质量的影响。该施工措施具有施工技术可靠、单桩承载力高、施工简便且工期短、工程造价低、能适应不同条件场地土的应用等特点。
This paper analyzes the reasons for various quality problems in the application of driven compacted pile in saturated loess soil,and puts forward the construction auxiliary measures for the application of driven compacted pile in saturated loess soil,which can effectively reduce the influence of horizontal load on the quality of pile.The construction method has the characteristics of reliable construction technology,high bearing capacity of single pile,simple construction and short construction period,low construction cost,and can adapt to the application of different conditions of site soil.
