摘要
对CFS夯扩灌注桩中关于桩端扩大头及人工持力层形成机理、桩体强度形成机理和复合地基加固机理进行了分析,并在桩体混合料配比试验的基础上,利用载荷试验验证了该类桩的加固效果。
The paper analyzes the enlarged end of pile, the formation mechanism of artificial bearing layer and pile intensity and the intensifying mechanism of composite foundation in CFS pile with rammed base, and improves the intensifying effect of the pile by the loading capacity test, based on the proportion test for the mixture of piles.
