摘要
超深大直径钻孔灌注桩以其单桩承载力高并能适应各种土质条件而得到越来越广泛的应用 ,但因其常需穿透多层地层及复杂地层而加大了施工难度 ,结合工程实例 ,介绍了超深大直径钻孔灌注桩施工技术。
The large caliber bored pile in super-depth is widely used because of its strong bearing capacity and good adaptation.However,it has difficult in passing the many complicated formations.This paper introduces the construction technology of large caliber bored pile in super-depth with concrete project.
