CFG Pile Composite Foundation In The Areas Of Applied Research Zhumadian

CFG pile composite foundation,for the purpose of dealing with soft ground to improve the bearing capacity and reduce settlement of foundation,have been widely used in the various foundation works.Based on reading carefully of the relevant theoretical,the interaction of bearing mechanism of piles,soil among Piles and cushion have been analysed in this article,giving deviation of bearing capacity estimate on code.Formula to the bearing capacity of composite foundation's been modified,considreing the distribution of pil e resistance,Constraint pile and the soil,additional stress of pile,side loading as well as the impact ofβcoefficient, combining with engineering practice.As an example of a practical project in Zhumadian region,the applicability,design and construction methods,construction process control, quality inspection and the effects have been analysed.The results has a certain reference value for the similar projects in Zhumadian region.
