基于现场试验,利用黄河三角洲某滩涂丰富的粉土资源,采用袋装粉土棱体+中间吹填粉土堤心斜坡堤结构在潮间带滩涂筑堤,对吹填粉土堤心进行地基处理,之后铺设沥青混凝土路面,建成3 km长的疏港一级公路,取得了较好的经济和社会效益.直接采用粉土充填土工织物袋,将常规的袋装砂筑堤技术升级为袋装粉土的筑堤技术,在粉土地区具有较好的推广应用前景.%Based on the field experiment,we use the rich silt resource in the Huanghe River Delta to build an embankment.Adopting the slope dike structured bagged silt prism plus filled silt dike core,we build a 3 km long grade I harbor road and achieve satisfactory economic and social benefit.The new dike-building technology,which upgrades the conventional bagged sand to the bagged silt by adopting directly the silt to fill the geotextile bags,shows a good application prospect in the silt area.
