摘要
结合广州华南路三期工程A4标朝阳立交特大桥桩基础工程,在抽心检测中发现2根桩基础的局部缺陷,采用的补强方法,阐述了复合注浆技术加固缺陷桩基础的工艺技术及其应用效果。
A pile foundation engineering case for super-large overpass bridge was illustrated; reinforcement was applied to local defects of pile foundation. The paper introduced the technology of composite grouting to reinforce the defect pile and the application effect.
