摘要
粉喷桩处理软土地基已在国内外得到较为广泛的应用，作为一种复合地基，对其工作机理仍有进一步研究的必要。本文利用实际工程标准贯入测试的结果，分析了粉喷桩对桩间可液化土层性状的影响；利用静力触探测试数据，讨论了粉喷桩施工前后桩间上端阻力和侧摩阻力的变化规律。
This paper studies the influence of powder-spray pile on the interpile soils. According to originalmeasurement results from some powder-spray pile projects, the effect of the pile on the behaviours of interpile liquefiable soils is discussed, and using data of the static cone penetration test, the increase of end resistance and side friction of soils among piles is analysed. borne tables are also given to compare the data beforeand after the ground stabilization.
