摘　　要：长螺旋钻管内泵压CFG桩,是近10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。根据多年的施工经验,对其进行了研究,得出长螺旋钻管内泵压CFG桩施工引起的环境岩土工程问题与施工工艺和施工场地的岩土工程条件有关。Pressure Pumped CFG Pile by continuous auger drilling is a kind of composite foundation new technology,which has been raised and developed in recent 10 years. But when this technology is applied in some regions in Zhengzhou,there appear to be various environmental geotechnical engineering problems in the actual process of project construction.Based on author's working experieuce,the reason of which is studied,and it is drawed that environmental geotechnical engineering problem is related to the construction technology and geotechnical engineering condition in construction site.

关 键 词：长螺旋钻管内泵压CFG桩 环境岩土工程问题 施工工艺 饱和粉土
