摘要
对粉喷桩在营口地区的加固效果进行了探讨与评价;并根据试验结果,与《建筑地基处理技术规范》[1]中复合地基承载力公式进行了对比分析,反算桩间土承载力折减系数β,针对营口市区不同地基土质条件,提出粉喷桩复合地基桩间土承载力折减系数β的取值范围,为营口地区粉喷桩复合地基设计提供参考。
Comparisons were made on the results of these single-pile composite foundation.This paper calculated the reduction coefficient ＂β＂ of the soil among piles by the formula from the Technical code for ground treatment of buildings that is used for calculating the bearing capacity of the composite foundation.Considering of the different ground soil condition in Yingkou district,the value standard of reduction coefficient ＂β＂ of the soil among piles for the powder-spray pile composite foundation has been presented.And the results could be the reference for designing the composite foundation in this district.
