【 摘 要 】

There won't be too much of an issue in the terms of bearing capacity, but may be a problem in the CFG pile construction for the CFG piles composite foundation design. basis on the CFG pile quality inspection standards, test the construction technology of CFG pile and reinforcement effect of composite foundation respectively adopting borehole core testing, pile reflection wave method to detect, single pile static load test. The results show that, the CFG pile as same as the grave pile have the effect of compaction reinforcement and substitution on the foundation. Due to the higher strength of pile body, the pile can effectively transfer the load to the deep soil layer to ensure the displacement of pile for foundation reinforcement when the compacting effect not good in the cohesive soil.
