摘　　要：长螺旋钻管内泵压CFG桩,是近十年来发展起来的一项复合地基新技术.然而当该技术应用到郑州地区的某些区域时却出现了环境岩土工程问题.经研究发现,这种问题的发生常常与饱和粉土层有关,因此通过颗粒分析、X射线衍射分析等试验手段对郑州地区饱和粉土层的工程地质特性进行了研究,进而探讨产生环境岩土工程问题的原因.Pressure pumped CFG pile raised and developed inlO years. But by continuous auger drilling is a kind of composite foundation new technology when this technology is applied in some regions in Zhengzhon, there appear to be various environmental geotechnical engineering problems. By studying, occurrence of this kind of problem is usually related to saturated silt layer. Therefore, carrying on particle analysis experiment,scanning electron microscope experiment and other test means, to study engineering geological property of saturated silt in Zhengzhou regions.

关 键 词：长螺旋钻管内泵压CFG桩 环境岩土工程问题 饱和粉土 工程地质特性
