挤扩支盘桩的工程应用

Engineering Application of Pile with Branches and Plates

介绍了挤扩多支盘桩在工程实例中的应用,并对工程同场地内的挤扩支盘桩与普通钻孔灌注桩进行承载力和沉降的对比试验研究.工程试验结果表明:在同等工程地质条件下,采用挤扩支盘桩能大幅度提高单桩承载力,减少沉降,具有良好的经济效益.

This paper introduces the use of cast-in-place pile with branches and plates in the actual engineering cases, and comparison is conducted between this particular type of usage and the common use of cast-in-place pile under the same working conditions. The result suggests that the piles with branches and plates can improve pile bearing capacity and reduce settlement, and thus produce better economic interests under the same geological conditions.
