后植入钢筋笼或钢管长螺旋CFG桩复合地基的工程实践

摘要

Together with project case, this paper proposes to improve bearing capacity of composite foundation by post-inserted reinforcing cage or CFG pile, especially for foundation treatment with geological conditions of soil cave or karst cave.%通过工程实例，介绍后植入钢筋笼或钢管长螺旋CFG桩复合地基方法，说明该方法可提高复合地基承载力，特别适合于在土洞、溶洞等特殊地质条件下的地基处理。
