摘　　要：预应力管桩桩身质量好、施工速度快、工程造价低,已在桩基工程中得到日益广泛的应用,某基坑支护工程通过对比悬臂钻孔灌注桩、钻孔桩加内支撑和预应力管桩加锚杆等不同方案后,决定采用预应力管桩方案,通过拉锚与管桩结合,完成了支护工作,取得良好的经济和社会效益。With the advantages of good pile quality, fast construction and low cost, prestressed concrete pipe-piles have been widely used in pile engineering. Through alternative comparison, prestressed concrete pipe pile was adopted in a foundation pit support work. And by combining anchor with pipe pile, support work was completed, achieving good social-economical benefit.
