摘要
CFG桩复合地基是一种较好的地基处理方法,广泛应用于铁路地基加固处理中。CFG桩是由水泥、粉煤灰、碎石、石屑(或砂)加水拌和形成的高粘结强度桩,它和桩间土、褥垫层一起形成复合地基。通过工程实践,阐述CFG桩复合地基处理的试桩施工、施工方法及其相关质量控制措施。
The CFG pile composite foundation is a better way used to treat ground, and is widely used in the reinforcement of railway ground. The CFG pile is made by mixing cement, fly-ash, crushed stone, rock crumb with water and is featured with high binding strength. The composite foundation is formed by combining CFG pile with soil between piles and cushion. This paper is to present the pile trial on the composite foundation of CFG pile, construction methods and related quality control measures by project practice.
