灰土挤密桩在处理湿陷性黄土地基中的应用

摘要

以具体工程为例,根据复合地基与灰土挤密桩的具体设计参数、施工方法等,制定了具体的试验检测方案。试验数据表明,复合地基桩间土的湿陷性得到了消除,桩体灰土的压实系数均大于0.93,复合地基承载力大于200 kPa,试验结果满足设计要求。%With the specific engineering as an example, according the specific design parameters and construction methods of composite foundation and lime soil compacting pile, the paper formulates specific experimental detection scheme. The experimental data shows that : the collapsibility among composite foundation piles is demolished, the coefficient of lime soil compacting pile is more than 0.93, the composite foundation bearing capacity is more than 200 kPa, which proves that the experimental results meet design requirements.
